%N a(n) = A176558(A175354(n)) = numbers m as reverse concatenations of divisors of numbers from A175354, where A175354 = numbers k such that reverse concatenations of divisors of k are nonprimes.
%e a(9) = 1264321 because A089374(9) = 12 and divisors of 12 are 1, 2, 3, 4, 6, 12; reverse concatenation of divisors A176558(12) = 1264321 is nonprime.
%Y Subsequence of A176558(n) = reverse concatenation of divisors of n.
