Triangulation isosig not parsed for big triangulations #23

Closed unhyperbolic closed 3 years ago

unhyperbolic commented 3 years ago

Computing and reconstruction the attached triangulation of S3 with 720 tetrahedra using the isosig doesn't work:

Triangulation(Triangulation('bigS3.tri.txt', remove_finite_vertices=False).triangulation_isosig())

yields

OSError: The manifold file -cqlv...aaaaa_ was not found.

bigS3.tri.txt

It works when dropping the "_" at the end.
