Go up one level in this thread


http://www.research.att.com/~njas/sequences/
search for 1,20,400

the answer for ply 5 is (4865609 ->) 815677 (this is without
ep, castling, or transpositions).  (I agree with 1,20,400,5362...)
the answer for the number of *move sequences* at ply 9
is <88867026005 (one of the other sequences there, calculated
without legality checking).

maybe I will do it with Dann's rules, although it will require
it bit of an EPD mutant...
