Hexiamond Pair 6-Rotary Oddities

Introduction

A hexiamond is a plane figure formed by joining 6 equal equilateral triangles edge to edge. There are 12 hexiamonds:

A hexiamond oddity is a figure with even symmetry formed by an odd number of copies of a hexiamond. Symmetrical figures can also be formed with copies of two different hexiamonds. Here are the smallest known oddities with 6-rotary symmetry for each of the 66 pairs of hexiamonds.
