6. “Diagonal Sums” of Odd and Even Summands






7. Prime Numbers as “Diagonal Sums“




Arithmetically, every possible Sum is formed from all possible Summands.
8. “Digital Squares” of SemiPrimes
The Triangle (half a square) of Vertical Primes x Horizontal Primes results in more attractive and “diagonally symmetrical” patterns:






Most intriguingly, only possibly comparable to the Strings of DNA, the Prime Factors with Last Digits 1 3 7 9 form this “Pattern of Regular Irregularity”: Products of Primes that act as “Vertical Twin Partners” in the ORTHOGONAL Pattern of Primes
9. The “SEQUENTIAL Factorisation” of SemiPrimes







just as 64 – but ‘tightened up’: no empty lines for Non-Primes.
65 shows SemiPrimes as “Prime Pair Partners” in the format of a “DIGITAL Table”.
66 shows the UNSORTED List and 67 the List of SORTED SemiPrimes,
using Prime 1 as secondary Sorting Criterion.
