%N Primes p for which p - 4 and p^3 - 4 are primes.
%C This is a subsequence of A046132: Larger member p+4 of cousin primes (p, p+4).

%e p = 11 is in this sequence because p - 4 = 7 (prime) and p^3 - 4 = 1327 (prime).
%e p = 17 is in this sequence because p - 4 = 13 (prime) and p^3 - 4 = 4909 (prime).
