Summary:
C: Mathematical software for low-dimensional topology
Description:
C: |-
<p>Regina is a software package for 3-manifold and 4-manifold topologists, with a focus on triangulations,
knots and links, normal surfaces, and angle structures.</p>
<p>For 3-manifolds, it includes high-level tasks such as 3-sphere recognition, connected sum decomposition
and Hakenness testing, comes with a rich database of census manifolds, and incorporates the SnapPea kernel
for working with hyperbolic manifolds. For 4-manifolds, it offers a range of combinatorial and algebraic
tools, plus support for normal hypersurfaces. For knots and links, Regina can perform combinatorial manipulation,
compute knot polynomials, and work with several import/export formats.</p>
<p>Regina comes with a full graphical user interface, as well as Python bindings and a low-level C++
programming interface.</p>
