Baiocchi Figures for Polyenns
A Baiocchi figure is a figure
formed by joining copies of a polyform and having the maximal
symmetry for the polyform's class.
For polyenns, that means the symmetry of a regular 18-gon,
or 18-way rotary with reflection.
If a polyenn lacks radial 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.
Here are minimal known Baiocchi figures for polyenns
of orders 1 through 4.
Not all these solutions are uniquely minimal.
