_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.

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