... Yep. It would be interesting to write a "minimally complex" algorithm to solve this problem. Upon getting the recursive formula, that's what I thought...
... Even the recursion was a bit of a mess to work out. :) It's easy (with diagrams:) to see that T(n) = 3T(n-1) plus the number of (a certain set of) graphs...

Hi, Today I was watching the Science Channel about Saturn. It was mentioned that the speed of light was 300,000 kilometers/sec. Now in miles it is 186,000 ...
