Ágrip:

We discuss the problem of bounding the number of 3-dimensional triangulations of the sphere as a function of the number of tetrahedra. We show how to establish an exponential bound in the case of locally constructible triangulations as well as causal triangulations. We also discuss the same problem in 4 dimensions.
