Pentahex Pair Tri-Oddities with Vertical Symmetry

A polyhex tri-oddity is a figure with ternary symmetry formed by some number of copies of a polyhex that is not a multiple of three. Torsten Sillke first studied them in 1996.

Here I show minimal known tri-oddities with vertical symmetry for pairs of pentahexes. Please write if you find a smaller solution or solve an unsolved case.
