Abstract

In combinatorial topology we aim to triangulate manifolds such that their topological properties are reflected in the combinatorial structure of their description. Here, we give a combinatorial criterion on when exactly triangulations of 3-manifolds with transitive cyclic symmetry can be generalised to an infinite family of such triangulations with similarly strong combinatorial properties. In particular, we construct triangulations of Seifert fibred spaces with transitive cyclic symmetry where the symmetry preserves the fibres and acts non-trivially on the homology of the spaces. The triangulations include the Brieskorn homology spheres Σ(p,q,r)\Sigma (p,q,r), the lens spaces L(q,1)\operatorname{L} (q,1) and, as a limit case, (S2×S1)#(p1)(q1)(\mathbf{S}^2 \times \mathbf{S}^1)^{\# (p-1)(q-1)}.
