COMMENTS

A123373[n] = Sum[ Sum[ Prime[i]^Prime[j], {i,1,n}], {j,1,n}].

LINKS

Table of n, a(n) for n=1..5.

EXAMPLE

A123373[n] begins {4, 48, 3598, 924780, 287358579128, ...}.

a(1) = 2 because 2 divides A123373[1] = 4.

a(2) = 3 because 3 divides A123373[2] = 48.

a(3) = 5 because 5 divides A123373[4] = 924780.
