Plover Figures for Polyhexes
A Galvagni Figure
is a minimal figure that can be tiled with a given
polyform shape in two or more ways.
A Plover Figure
is a Galvagni Figure in which the tiles are not merely
congruent but identical; that is, they are not distinct mirror images.
For tiles with reflective symmetry, a Plover Figure
is the same as a Galvagni Figure.
Corey Plover worked out Plover Figures for polyominoes.
You may see the tetrominoes
and the hexominoes
at Erich Friedman's Math
