Baiocchi Figures for Polyaboloes

A Baiocchi figure is a figure formed by joining copies of a polyform and having the maximal symmetry for the polyform's class. For polyaboloes, that means the symmetry of a square.

Claudio Baiocchi proposed the idea in January 2008. Baiocchi figures first appeared in Erich Friedman's Math Magic for that month.

Here are minimal known Baiocchi figures for polyaboloes of orders 1 through 5. Not all these solutions are uniquely minimal.
