Unfortunately these images are likely to be impossible to read on screen, but I will include the source file also for reference.
The following shows the distribution of primes (shown as “P” for those beyond 43, or as the primes to 43 for their first instances) and non-primes (lowest prime factor shown) to 43^2 (highlighted to 43^2 – 1), with a few more lines of non-primes and “possible primes” (shown as “PPP”):
The point of posting these is to allow further contemplation of patterns of elimination with a larger set of numbers.
Still nothing particularly brilliant to offer. 🙂
