Conjecture: The sequence is finite, with 16 being the last term.
If A182049 is finite, then this sequence is finite. If 41 is the largest term in A182049 (as is conjectured), then 16 is the largest term of this sequence. - M. F. Hasler, May 04 2015
EXAMPLE
13! = 6227020800. 13 and 6227020800 have no digits in common, so 13 is a term of the sequence.
