Sorry i guess i didn't refresh the page ii had only seen the link.
So 10 different coloured bead . A,B,C,D,E,F,G,H,I,J. (Just to make it easier :) )
Is it just... Since non of the letters are the same.
$${\mathtt{10}}{!} = {\mathtt{3\,628\,800}}$$
and if i was do 1!,10x it would be same
3628800.Too much >.<
