%N A358174 Smaller of a pair of numbers (m, m+1) such that both are products P of composite prime powers with omega(P) > 1.
%C A358174 a(n) = A286708(k), where k is a position of 1 in A358173.
%e A358174 a(1) = 675, since 675 = 3^3 * 5^2 and 676 = 2^2 * 13^2 are the smallest products of at least 2 composite prime powers that differ by 1.
%e A358174 a(2) = 9800 since (3^4 * 11^2) - (2^3 * 5^2 * 7^2) = 1.
%e A358174 a(3) = 235224 since (5^2 * 97^2) - (2^3 * 3^5 * 11^2) = 1.
