nCr : Out of N, Choose R : Just Choose, When I choose I don’t care about order. Or you can remember that permute means “change the order of”. In addition remember that there will certainly be more ways in which to do things when order matters, hence when you permute, you lose one of the terms in the denominator, thus yielding a larger number of options when you permute.
