A137701  Semiprime(n)^prime(n).
A111096  Sum of semiprime(n)^prime(n)

The two above should crossreference each other.

new: sum of more than one distinct A137701 (comment: A111096 is a subset).

I'm especially interested in the subset of primes in the new sequence.

Would anyone like to extend the below, especially to search for primes?

{n}   sum
1,2    4^2 + 6^3 = 232
1,3    16 + 59049 = 59065
2,3    216 + 59049 = 59265
1,2,3  4^2 + 6^3 + 9^5 = 59281 which is prime

1,2,3,4   10059281 = 4^2 + 6^3 + 9^5 + 10^7, which is prime
