%N a(n) is the smallest number k having n prime distinct divisors such that k is divisible by the square of the sum of its prime divisors.
%C n > = 3, because if n = 2 then k = p^a * q^b, where p and q are distinct primes and (p+q)^2  k => p+q ==0 (mod p) or 0 (mod (q), but p==0 (mod q) and q==0 (mod p) are impossible.

%e a(4) = 37026 because the prime distinct divisors of this number are {2, 3, 11, 17}, (2 + 3 + 11 + 17)^2 = 1089, and 37026 = 1089*34.
