It is easily verified using PariGP that
[In fact, most of them have a prime factor less than 100. The few remaining numbers with no prime factors less than 100 also have small prime factors, the largest minimal factor being 2557.] The term in the AP for n = 5 has no prime factors less than 10^{8}. But it is composite by the BPSW test. Last fiddled with by Dr Sardonicus on 20220201 at 20:20 Reason: clarification

CPAP3 updated to 15,004 decimal digits (prerelease)
I now updated the "oldest" in this series: CPAP3  to 15,004 decimal digits.
Because I am waiting on the formal Primo proofs for the two out of the three, I will post it to UTM Primes around Friday.
