[net.math] Plato product problem

trt (07/23/82)

Plato (as I recall) noted that 7! == 7 * 8 * 9 * 10.
That is, a descending product from 7 == an ascending product from 7.
He wondered if there were other integers N such that
	1 * 2 * ... * N == N * N+1 * ... * B
for whatever B is needed.

I wrote a program (sorry) which convinced me that
7 was the only such integer.  I forget what the program did.

Anyway.  *Are* there other integers with this property?
