%N Ordered factorizations over hook-type prime signatures with exactly three distinct primes (third column of A098348).
%C a(n) can also be calculated by transforming (3,18,8) applying the binomial transform twice. Cf. A098384.

%F a(n) = 2^n * (n^2 + 8*n + 13). - _James Rayman_, Mar 27 2021
%e The hook-type least prime signatures with exactly three primes begin 30,60,120,...; therefore sequence begins A002033(30,60,120,...) = 13,44,132,...
