%H Matthew Conroy, <a href="/A066419/b066419.txt">Table of n, a(n) for n = 1..1000</a>

%e The sum of the decimal digits of 5! is 1+2+0=3 and 3 divides 120, so 5 is not in the sequence; the sum of the decimal digits of 432! is 3897 = (9)(433) and 3897 does not divide 432!, so 432 is in the sequence.
