COMMENTS

If n > 7, a(n) is a 3-PRP.

LINKS

Table of n, a(n) for n=0..12.

Cino Hilliard, Primes in (x^n)! + m.

EXAMPLE

For n=1, (2^1)! + 0 = 2 a prime. So 0 is the second entry in the sequence.

For n=9, (2^9)! + 683 is a 3-PRP. So 683 is in the sequence.

PROG

The Gcc program in the link uses Gmp mpz_nextprime to generate the sequence. Pfgw was also used as a verification.
