snappy-manifolds

library1.4pypypi✓ verified 80d ago

A database of snappy manifolds for use with the SnapPy library. Current version 1.4 expands OrientableCuspedCensus and CensusKnots to include all 10-tetrahedra manifolds and adds the RibbonLinks census. Maintained by the 3-manifolds community.

Load the first manifold from the orientable cusped census and print its name and volume.

import snappy from snappy_manifolds import orientable_cusped_census # Load a manifold from the census M = orientable_cusped_census[0] print(M.name(), M.volume())

Debug

Known issues

breakingIn version 1.4, OrientableCuspedCensus and CensusKnots expanded to include all 10-tetrahedra manifolds. This may change numeric indices and increase memory usage.

fix

If your code depends on specific indices (e.g., orientable_cusped_census[100]), verify the new ordering and update accordingly.

affects: >=1.4

deprecatedSome older census names may be deprecated in future releases; check documentation for aliases.

fix

Use the current census names as listed in the documentation.

affects: >=1.0

gotchasnappy-manifolds does not automatically load all submodules on import. You must import specific submodules explicitly.

fix

Use e.g. 'from snappy_manifolds.link_exteriors import LinkExteriors' instead of relying on the top-level package.
