Feb 21, 2012 at 3:02 comment added Igor Rivin @Richard: does this mean triangulations which are manifolds, or DISTINCT (topologically) manifolds?

Feb 21, 2012 at 0:34 comment added Richard Stanley A related result is due to Gil Kalai. He showed that the number of triangulated manifolds (of any dimension) with $n$ labelled vertices is $2^{2^{.69424\cdots n(1+o(1))}}$. See springerlink.com/content/78044667x381777g.
Feb 21, 2012 at 0:27 comment added Joseph O'Rourke Following up on Ryan's pointer, Burton's paper "The Pachner graph and the simplification of 3-sphere triangulations" (arxiv.org/abs/1011.4169) includes an algorithm for "isomorph-free generation of all 3-manifold triangulations of a given size."
Feb 20, 2012 at 23:52 comment added Ryan Budney Ben Burton works on this problem. I think he's pretty convinced that even for spheres, the growth-rate is super-exponential. He certainly has numerical evidence but I suspect he might eventually have a proof.
