Values in the chart above are all distances between points on the perimeter (the Frame) of the Athena engraving.  This is the set of unique values (eleven out of thirteen in all), which are then rearranged by size. The six smallest values (in color emphasis) are all blatantly major processional code numbers, meaning that they divide evenly into 25920 -  the number of years in one full cycle of the Zodiac, based upon the full cycle of equinox precession.
                             On this first level of accuracy:
constellations shift one degree in                      72 years,                                                 
one of the twelve Zodiac houses in              2,160 years, 
1/6 of the heavenly mill of constellations in   4,320 years. 
The Zodiac is a cycle of                            25,920 years. 

Since these numbers are somewhat inaccurate by today's standards - we wonder if they force a limit on the Frame's accuracy. As usual, we needn't worry. The Frame comes through in an impressive fashion, as the reader will see.

The famous Osiris Number 432 and 25,920 

The Osiris Numbers synchronize the processional cycle with the clockworks of a 360-degree circle, and a 24-hour day, impressing upon nature the seal of Creation. The most prominent Osiris Number has always been 432. For example, the Great Pyramid is apparently meant to be a proportional model of the Northern hemisphere, scaled down to 1:  43,200. This number is twice the 21,600 minutes (and also nautical miles) in 360 degrees around the Earth, and half the number of seconds in a 24-hour day (86,400).

Why 432?

a)
Many writers automatically associate the hexadecimal system with the division of the circle into 360 degrees, despite the fact that 360 is not a whole multiple of 16, the hex base. The lowest number divisible into whole multiples of both 16, and 36 (one-tenth of 360) is 144. However, 144 is not a whole multiple of either 54, or 108, which like 36 are found as angles on a regular 5-pointed star drawn over a cross. This is a job for 432.  Here, we can observe that 432 contains whole multiples of all the major angles found on a regular 5-pointed star (pentagram), drawn over a cross:
                  (18   36   54   72   108   144)
Here is the list of all numbers dividing evenly into 432: 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, and 216.  Figuratively speaking, 432 is a major intersection.

b)
Using a pair of compasses, the radius of a circle divides its circumference into six even parts! This may be the geometric key to 432's importance. As 4,320, it is one-sixth of the Zodiac's circle of 25,920 years, and one-fifth of the number of nautical miles in the circumference of Earth.

         

  First, 108 is a link carrying the spirit of Osiris to the following group.         
  

  Of course, 360 is an important Osiris Number.
  The first two non-Osiris numbers in this set combine into a multiple of 36, an Osiris number.

  252  = 36 * 7
             

Above - there it is again - the number 432

 All the non-Osiris numbers of the set together!       

               
  Let's make use of the below pie chart.
 
  a) The five longest unique values of the Frame add up to 720- a major Osiris Number.
  b) Not only is this 720 a whole multiple of 36, but also so are four of its subsections.
   
                                                                                                        252= 36  * 7
                                                                                                        288= 36  * 8
                                                                                                        432= 36  * 12
                                                                                                        468= 36  * 13
 720= 36 * 20

 c) The average of the five segments is 144 per segment.
      The total divides into two subsections, which are also multiples of 144:
 288 = 144  * 2
                                                                                                        432 = 144  * 3
                                 

                                                                 
     The character of this set of 720 is that leads again and again to 36 and 144.  
       
     720 * 36  = 25,920     The duration of one processional cycle.
    
      But, what about the cycle of 25,920 years, and 144?  Anything special?

         Level 2 - the Processional Cycle of 25,776 years

On a higher level of accuracy, the precession takes:
 71.6    years for 1 degree,
 25,776     years for the entire processional cycle
 
 25,920
    - 25,776   = 144 years, or two degrees. Herein is our answer, as 144 is the difference in duration between level 1 and level 2. This difference is itself an Osiris number.
         
            180 * 144 = 25,920        179   * 144  = 25776
                                                  71.6 * 360  = 25776
 
Is the Frame really indicating a second level of accuracy for the precession?

At this stage, we have to return to the standard pie chart of the Frame.

If 16 and 113 plus its neighbors create symmetry and meaning across this pie chart, the two slices of the pie next to them (175 and 146) do the same thing. They look like two inverse cones. They have the virtue of being symmetrical, as the spaces in between them measure a total of 452 on the left, and 453 on the right.  The two values cannot be placed more symmetrically in the diagram than what we have now.



175 * 146  = 25,550

What is attached to the right of 175 and 146? _  Twice 113.

25,550 plus twice 113 equals 25,776. 

Level 3 - the Processional Cycle of 25,770.0594years

             

The below link cites up to date information on the duration of the precession of equinoxes. The heavenly mill of stars processes .0 139 697of one degree per year.
http://scienceworld.wolfram.com/physics/PrecessionoftheEquinoxes.html  

Does the Frame have a pointer to this modern value for precession?

Indeed, we do have a 139segment on the Frame. It is part of the section of seven consecutive values totaling 697(see diagram above).

 360 degrees divided by .0139697 equals 25,770.059485 years

With respect to .0594, the fraction of a year left over 25,770, and we have a section of 297, which just happens to be exactly one-half of the 594 from above. Every segment in this section is a multiple of 27.
     
         27 * 11 = 297

                                   

Thus, our attention is brought upon the fact that 594 is a multiple of 27, too.

27 * 22 = 594

As 27 seems for some reason important here - what about its neighbors?

81 + 139 = 220
                                   

The 27 segment multiplied by the total of its two immediate neighbors

27 * 220  = 5940

To summarize: a) 0139697 degree is the yearly rate of precession. b) 25,770.059485 years is the duration of one processional.
On the Frame 139 is instrumental to recording the rate of precession, with 27 as the first segment before 139 in the relevant section of segments.
Next, 27 was instrumental to recording the exact duration of one processional cycle, in conjunction with both of its neighbors, one of which is 139.
Each piece of evidence reinforces the rest of it. All these individual pings of resonance result in a final symphony of order. It is important to know that some combinations in the Frame give 220, for if we add this 220 to the 25,550 given by the inverse cones of 175 and 146, we get the exact number of whole years in the processional cycle - 25,770as in the diagram below. This is just a switch to the other side of the inverse cones of 175 and 146, which gave us the 25,776 years in addition with neighboring segments.

175 * 146  = 25,550
25, 550 + 27 + 54 + 139= 25,770



This is the time to ask the reader to look back over all the ground we have covered in four chapters on just the numeratic aspects of the thirteen Frame segments. Could such expanse of correlated data be just a confluence of chance? Does the reader believe in miracles?
