{A006450(i) : A007953(A006450(i)) in A000040}. [From R. J. Mathar (mathar(AT)strw.leidenuniv.nl), Aug 03 2009]

EXAMPLE

Prime(prime(6)) = 41. 4+1=5, prime. So 41 is in the sequence.

(PARI) sodip(n) = {

local(s=0, a, x, y, j, p);

for(x=1, n, p=prime(prime(x)); a=eval(Vec(Str(p))); y=sum(j=1, length(a), a[j]); if(isprime(y), print1(p", ")); )

}

CROSSREFS
