Hi,(adsbygoogle = window.adsbygoogle || []).push({});

I was wondering if anyone can help me out here....

I have a series of numbers 1 to 16,

What I would like to know is the formula to finding out how many different sequences I can make with them.

For Example:

1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16 would be one sequence

2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,1 would be another sequence

I thought that if I multiplied 16 by itself, 16 times this would give me the number of sequences I looking for but the answer I got was

18446744073709551616....This cant be right...right?

Anyway thanks for the help if any given.
