# Galvagni Figures for Polypentagrams

A *polypentagram* is a figure made of regular pentagrams 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.
