# Galvagni Figures for Polypents

A *polypent* is a figure made of regular pentagons 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.
Many of the polypent Galvagni figures up to order 5 were found by
Scott Reynolds or Erich Friedman.

Here are minimal known Galvagni figures for polypents.
