Abstract
We build a combinatorial four-dimensional torus with 31 vertices, different from that obtained by Kühnel and Lassman. Our torus has also a vertex transitive group action but the symmetry group is of order 2 × 3 × 31, different from 2 × 5 × 31 for the symmetry group of the Kühnel–Lassmann torus. Furthermore, we give a geometrical description of this torus, as well as various results concerning triangulations of tori of dimensions 2 and 3.
