If you have an older version on the TI30x Solar (not TI30Xa or newer) then you must use a different key sequence for nPr/nCr.
52 [2nd][x/y] 5 [2nd][nCr] gives 2598960 (the x/y button is above the Pi symbol on my version).
8 [2nd][x/y] 3 [2nd][nPr] gives 336
This took me forever to find out, so hopefully it will help someone!
