Tri-Oddities for Heptiamond Pairs

A tri-oddity is an arrangement of copies of a polyform with ternary rotary symmetry or better, using a number of copies that is not a multiple of 3.

Here I show the smallest known tri-oddities that can be formed by copies of two heptiamonds, using at least one of each. If you find a smaller solution, please write.
