# Polydodec Oddities

A *dodecagon* is a polygon with 12 sides.
A *polydodec* is a figure made of regular dodecagons joined
edge to edge.
An *oddity* is an arrangement of an odd number of copies of a
polyform so as to form a figure with binary symmetry (or higher).
Here I show minimal known simple mirror oddities for polydodecs.
