censuslookup — Search for triangulations in Regina's census databases
This utility searches for the given 3-manifold triangulations in the various census databases that are shipped withRegina.
You should present the trianguations using their isomorphism signatures. These are short text strings that identify the triangulation uniquely up to combinatorial isomorphism (i.e., up to relabellings of the tetrahedra and/or their vertices).
From the graphical user interface, you can view the isomorphism signature
of a triangulation by switching to the Composition
tab in the triangulation viewer. From Python you can fetch the
isomorphism signature of the triangulation
For a full and precise specification of isomorphism signatures, see
Simplification paths in the Pachner graphs of closed
orientable 3-manifold triangulations, Burton, 2011,
All database matches (if any) will be written to standard output.
