COMMENTS
A318366(n) computes a sum over the divisors of n in such a way that A318366(n) only depends on the prime signature of n. A025487 lists least numbers with a given prime signature with the exponents in nonincreasing order. This sequence hence shows this sum over divisors for distinct prime signatures.

EXAMPLE
a(8) = A318366(A025487(8)) = A318366(24) = 20 (See example of finding A318366 at that sequence).
