A semimonomial group over a ring `R` of length `n` is equal to the semidirect product of the monomial group and the group of ring automorphisms. The multiplication of two elements `(\phi, \pi, \alph…

A few files still use `$...$` for math instead of backticks in docstrings.
We can make the source more uniform by replacing it.
In follow-up tickets,
the function `sage.misc.sagedoc.process_do…

Implementation of two conformal models of hyperbolic geometry (half plane, disc) and actions of their isometry groups.
The actual file is almost complete for working with the hyperbolic plane as th…

Theorems `tgsss1`, `tgsss2`, and `tgsss3` are true, but I don't think they prove what was intended.
The comment currently describing theorem `tgsss1` says it is "Third congruence theorem: SSS (Sid…

Move a morphology/segment tree in space.
We already have some support for this using `pw_lin` and `isometry`, it would be useful to have the option to modify the morphology itself.

As of this writing, transformations are just [isometries](https://en.wikipedia.org/wiki/Isometry), so a combination of translation and rotation. I think we should support arbitrary transformation matr…
