Introducing Regina, The 3-Manifold Topology Software

Abstract

An overview is presented of Regina, a freely available software package for 3-manifold topologists. In addition to working with 3-manifold triangulations, Regina includes support for normal surfaces and angle structures. The features of the software are described in detail, followed by examples of research projects in which Regina has been used.
