%N Numbers k such that the partition number p(k) = A000041(k) is a term of A057109, i.e., it is not a divisor of the factorial of its greatest prime factor.

%C There are no more terms below 3000.

%e p(14) = 3^3 * 5, but 5! has only one factor 3.

%e p(19) = 2 * 5 * 7^2, but 7! has only one factor 7.

%e p(24) = 3^2 * 5^2 * 7, but 7! has only one factor 5.

%e p(28) = 2 * 11 * 13^2, but 13! has only one factor 13.

%e p(118) = 11 * 197 * 827^2, but 827! has only one factor 827.
