Inserted Groups
Baumslag-Gersten Group
Checked: No Notes: --
Braid Group
Checked: No Notes: --
Cyclic Group
Checked: No Notes: --
Dicyclic Group
Checked: No Notes: I added two different implementations, one with explicit invers elements and one without. I think the second one is the right one. The computation of the first implementation results in a GB with size 2812, the second one with size 901.
Dihedral Group
Checked: No
Notes: It follows, that a^{-1} = a^{2n-1} and that b^{4} = 1 (second equation) --> b^{-1} = b^{3}
My question is, do I have to implement the last equation with b^{3} instead of b^{-1} or should
I use 4 generators (a invers to c, b invers to d)?
von Dyck Group
Checked: No Notes: A useful reference is still missing
Free abelian Group

Free Group
Checked: No Notes: --
Fibonacci Group
Checked: No Notes: --
Heisenberg Group
Checked: No Notes: The matrix in the description will be added as a picture, then it will look much better. At the moment we cannot upload pictures to the server, but I contacted Stefan, there will be a solution soon.
Higman Group
Checked: No Notes: --
Ordinary Tetrahedron Groups
Checked: No
Notes: I used the implicit invers elements: We know that x^{e_1} = 1, it follows that x^{e_1 - 1} is the invers, and so on..
Please check, if I'm right.
