Galvagni Figures & Reid Figures for Hexominoes

A hexomino is a figure made of six squares 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. A Reid figure is a Galvagni figure without holes.

Most of the hexomino Galvagni and Reid figures were found by Michael Reid of the University of Central Florida and Erich Friedman of Stetson University. Corey Plover found the 12-tile Galvagni figure below.
