摘要：

We give an estimate of the number of simplicial three-dimensional manifolds as a function of the number N of tetrahedrons used to build the manifolds. By use of a new Monte Carlo method for generating these manifolds we provide evidence that the number is exponentially bounded if the topology of the manifold is restricted to that of S3.
