%N A375647 Products of prime 8-tuples (p, p+2, p+6, p+12, p+14, p+20, p+24, p+26) where p = A022012(n).
%C A375647 Primes p in A022012 belong to either 17 or 167 (mod 210).
%C A375647 Therefore a(n) is either congruent to the product of residues {17, 19, 23, 29, 31, 37, 41, 43} (mod 210), or {167, 169, 173, 179, 181, 187, 191, 193} (mod 210), so a(n) is congruent to 121 (mod 210).
%C A375647 Gaps between prime factors have a symmetric arrangement {2, 4, 6, 2, 6, 4, 2}.
