Let $t(P)$ be the number of straight edge triangulations of a planar point set $P$. It is known that $t(P)\geq \Omega(2.4^n)$, where $n=|P|$. We give an algorithm that computes $t(P)$ in time $O(n^2 2^n)$. Thus the algorithm is ``aggregative'' in the sense that it determines the cardinality of a set substantially faster than by enumerating the elements.
