Upper limit for exact factorial

[Joe Horn]

All recent firmware revs seem to allow CAS to calculate up to 1000! but no greater exact factorial, returning infinity for 1001! or higher. But the rev 7820 emulator seems able to go up to 1006!. That's a strange difference between the hardware and emulator, apparently unrelated to amount of available memory.

hi Joe,
in fact in the Prime, in Home I still get 1007! -> 1E500, in CAS I get infinity up to 1001...
I'll try on Emulator in the afternoon, I'm curious...

However, permutation for 1001 people are indeed ...too :-)
