This is simple permutation...
40!
yes 40 factorial.
the first person may sit on any of the 40.
the next on any of the 39 remaining.
the next on any of the available 38 and so on...
hence leading to 8.15915283247898e+47
this may sound kinda cracked but the answer is:
815915283247897734345611269596115894272000000000
