%N Numbers k such that A336456(n) is not equal to Product_{p^e|n} A336456(p^e). Here each p^e is the maximal power of prime p that divides k, and A336456(n) = A335915(sigma(sigma(n))).
%C Numbers at which points A336456 is not multiplicative.
%C Note that in contrast to A051027 (case in A336548), here Product_{p^e|n} A336456(p^e) can be also less than A336456(n), not just greater than or equal.
