# Galvagni Figures for Rotary Polyhexes

A polyhex is *2-rotary* if it looks the same
when rotated 180°,
and *3-rotary* if it looks the same
when rotated 120°,
It may also have mirror symmetry or 6-rotary symmetry (60 °).
A *Galvagni Figure*
is a shape that can be tiled by a polyform in two or more ways.
The ways may be isomorphic, so long as they have different positions.
They were proposed by Jeremy Galvagni and first appeared
at Erich Friedman's site Math Magic.

Here I show minimal known Galvagni Figures for
rotary polyhexes.
Thanks to Mark Smith for suggesting this page.
