snappy

Kernel

Minor

- dual_curves should really cache it’s result and have this used by drill
- One should be able to convert a SymmetryGroup to a Sage permutation group.
- Also, the SymmetryGroup presentation function should be wrapped. There is code for this in the old SnapPeaPython.

Ambitious

A new basic (sub)class: S3Knot (and/or S3Link).

Consider adding a HeegaardSplitting class

Consider merging our t3m project and normal surface code into SnapPy.

Redo much of Snap in the context of Sage/SnapPy.

- Add a method for computing tetrahedron shapes to arbitrary precision.
- Add methods for computing invariant trace fields and related number fields.
- Add a method which implements and extends Harriet Moser’s algorithm to allow SnapPy to prove that a manifold is hyperbolic.
