# Baiocchi Figures for Polypents

A *Baiocchi figure* is a figure
formed by joining copies of a polyform and having the maximal
symmetry for the polyform's class.
For polypents, that means the symmetry of a regular decagon,
or 10-way rotary with reflection.
If a polypent lacks apothemal bilateral symmetry, its Baiocchi figures
must be Galvagni figures or contain Galvagni figures.
Claudio
Baiocchi proposed the idea in January 2008.
Baiocchi figures first appeared in Erich Friedman's
Math Magic for that month.
Károly Hajba first studied polypent Baiocchi figures
and found many of the solutions below.

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