A136690, the last non-zero digit of n! in base 3, has cross-refs for 
the last non-zero digit of n! in bases 4 through 16.

It might be interesting to consider the last nonzero digit of n! in
other bases. To start the ball rolling, I have developed a clever
algorithm for finding elements of A000012, the last nonzero digit of
n! in base 2.
