# Galvagni Figures for Polyhepts

A *polyhept* is a figure made of regular heptagons 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 polyhepts.
The black tiles have no Galvagni figures.
