A Baiocchi Figure is an arrangement of copies of a polyform to achieve the highest symmetry class for its type of polyform. For polyiamonds, this means 12-fold symmetry, 6-rotary and mirror.
Here I show the smallest known Baiocchi Figures that can be formed by copies of two heptiamonds, using at least one of each. If you find a smaller solution, please write.
