The diagonalization of the cyclotomic polynomials

$a=38$ is the largest $a$ with a prime for $b > 0$ at the moment.

No furhter factors found

@Peter It is a sphenic number, 2*3*337. Moreover the sum of digits 6 divides 2022, and 2022/6 = 337 is the prime expressible as 2^(2^3) + 3^(2^2).

Just in case it gets frozen, I will remind that moderators can unfreeze chatrooms - so you can ask some moderator (from any site) whether they would be willing to do so.

@Peter Upvoted. But I'm afraid there is a lack of broad interest in cyclotomic polynomials.
