Represents a layered solid torus in a triangulation.
A layered solid torus must contain at least one tetrahedron.
Note that this class only represents layered solid tori with a (3,2,1) at their base. Thus triangulations that begin with a degenerate (2,1,1) mobius strip and layer over the mobius strip boundary (including the minimal (1,1,0) triangulation) are not described by this class.
All optional StandardTriangulation routines are implemented for this class.

Returns a detailed text representation of this object.
This text may span many lines, and should provide the user with all the information they could want. It should be human-readable, should not contain extremely long lines (which cause problems for users reading the output in a terminal), and should end with a final newline. There are no restrictions on the underlying character set.

inherited |
Returns a short text representation of this object.
This text should be human-readable, should fit on a single line, and should not end with a newline. Where possible, it should use plain ASCII characters.
__str__()

Returns a short text representation of this object using unicode characters.
Like str(), this text should be human-readable, should fit on a single line, and should not end with a newline. In addition, it may use unicode characters to make the output more pleasant to read. This string will be encoded in UTF-8.
