Baiocchi Figures for Polypentagrams

A Baiocchi figure is a figure formed by joining copies of a polyform and having the maximal symmetry for the polyform's class. For polypentagrams, that means the symmetry of a regular pentagon, or 5-way rotary with horizontal reflection. 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 polypentagrams with 1 through 4 cells. Not all these solutions are uniquely minimal.
