Another relevant paper is
D. Berend and C. F. Osgood, On the equation P(x) = n! and a Question of Erdős, J. of Number Theory 42 (1992), 189 - 193.

_Dear Frank,
I think that a very useful paper in this direct is "On polynomial-factorial diophantine equations" by Daniel Berend and Jørgen E. Harmse in journal " Trans. Amer. Math. Soc.", 358 (2006), no.4, 1741-1779.
Best regards,
Vladimir

Cf. A061030 - A061032.
IMO if it is proved that those are the only such numbers the info should
just be added to these seqs.
