Baiocchi Figures for Polyhendecs
A polydec, or polyhendecagon, is a figure
formed by joining regular hendecagons (11-sided polygons) edge to edge.
A Baiocchi figure is a figure
formed by joining copies of a polyform and having the maximal
symmetry for the polyform's class.
For polydecs, that means the symmetry of a regular hendecagon,
or 22-way rotary with reflection.
If a polyhendec lacks apothegmal bilateral symmetry, its Baiocchi figures
must be Galvagni figures or contain Galvagni figures.
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 polyhendecs
of orders 1 through 4.
Not all these solutions are uniquely minimal.
