just found out the factorization of 65,535 is 3 × 5 × 17 × 257
ffff
the factorization of 4,294,967,295 is 3 × 5 × 17 × 257 × 65537, too
ffffffff
@tef pattern appears a lot in powers of two of powers of two, but not reliable
@tef off-by-one powers of two in the factorizations of off-by-one powers of two
@tef subcase of proth primes
@tef i wanna figure out whether this is a statistical pattern now
