EXAMPLE
13 is a term because 13 is the 6th prime and the sum of the first 6 primes^11+1 = 2079498398712 when divided by 6 equals 346583066452 which is an integer.
MATHEMATICA
t = {}; sm = 1; Do[sm = sm + Prime[n]^11; If[Mod[sm, n] == 0, AppendTo[t, Prime[n]]], {n, 100000}]; t (* Derived from A217599 *)
PROG
(PARI) is(n)=if(!isprime(n), return(0)); my(t=primepi(n), s); forprime(p=2, n, s+=Mod(p, t)^11); s==0 \\ Charles R Greathouse IV, Nov 30 2013
