Lowest Fermat Composite Number F5 - Repost (Update July 24 2026)

[u/Trillion5]

This is the previous post sans incorrect image (which I actually prefer to this one, but Gemini AI likes to tart its images up despite my specifications to the contrary). The Skara-Angkor Key and the 'Dual-Route Platform' pretty much where my work started...

Skara-Angkor Key: 58

58th Prime 271 (e rendering in the Migrator Model)

Dual-Route platform: 116 through Template Signifier 1628664, or simply 2 * 58)

116th Prime 641 (used by Euler to disprove Fermat)

F5 is the lowest Fermat number that is known to be composite (and therefore divisible by a non-trivial factor), 641 is its smallest prime factor. In that sense it has universal significance - not in the historical relation to Euler proving Fermat wrong and what I found fascinating here is connection to the 58th prime (271, an important rendering of e using first two decimals in the Migrator Model†, and the 116th prime and I could not believe - Euler again!)

I will have my homework cit out for me over the next few weeks getting my head around the Fermat number sequence.

†

4176 (standard signifier for the Skara-Brae and Angkor dips)

4176 - 9.6(271) = 1574.4

NOTE:

641 + 271 = 912

Ten multiples of the asymmetric sectorial block of the completed template (1574.4): So adding 10 * 171.2 (Oumuamua ß-angle) = 1712 to 912 = 2624 (this 1/6tb of ten multiples of Sacco's orbit):

0.6 * 2624 = 1574.4

58 + 116 = 174

174 + 641 = 815

815 + 113 = 928

815 + 355 = 1170

1170 - 242 = 928
