%N A339855 Primes p such that the absolute value of the fraction A241014(A000720(p)) / p is a record low.
%C A339855 So-called near-Wall-Sun-Sun primes. Each term is "nearer" to being Wall-Sun-Sun than all smaller primes.
%C A339855 If any Wall-Sun-Sun primes exist, this sequence terminates at the smallest Wall-Sun-Sun prime.
%C A339855 If you start from p=7 (not p=2), then the sequence will start 7, 13, 17, 41, ... instead.
