a(1)=1, a(n) = a(n-1) + (p-1)*p^n/2-1 if n is even, otherwise a(n) = a(n-1) + p^(n-1/2), where p=5. A133629

Numbers whose base-b expansions, for both b=3 and b=4, include no digits other than 1 and b-1. A262958

Numbers of the form p·q, where p is prime and q=(p^k-1)/(p-1) is also prime for some integer k>1. A330832

Nonprime-powers k such that, for any prime p dividing k and m = 1+floor(log k/log p), rad(p^m (mod k)) divides k, where rad = A007947. A381750
