Galvagni Figures for Polydecs
A polydec is a figure made of regular decagons joined
edge to edge.
A Galvagni figure is a figure that can be tiled by a polyform
in more than one way—a kind of self-compatibility figure.
Galvagni figures first appeared in Erich Friedman's
Math Magic
for November 2004.
Here are minimal known Galvagni figures for polydecs.
