The number of possible pairs of people in a room of n people is about n^2/​2, not n factorial. 10^2 is many orders of magnitude smaller than 10! :)
(I think you are making the mistake of multiplying together the contacts from each individual, rather than adding them together)
lol I thought that 10! was a surprise, rather than a factorial...
