Amusing Permutation representations of group extensions.
Abstract: We study the binary extensions of the motion groups of polygons and polyhedra, by representing the groups as string diagrams with decorations.
The method is an application of the Krasner-Kajouline theorem
in which a finite group of order nk can be represented into a semi-direct product $(S_k)^n * S_n$
where the second factor acts upon the first by permuting coordinates.
