Say we have sterling numbers of the first kind where we're given s(n, n-2) = 2(nC3) + 3(nC4)(adsbygoogle = window.adsbygoogle || []).push({});

for n greater than or equal to 4.

I know the left hand side we have n people, and we wish to seat them at n-2 circular tables, but I need help with the right hand side! I would greatly appreciate any help at ALL!
