Hexiamond Pair Dual Orthogonal Edge-Centered Oddities

Introduction

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 edge-centered dual orthogonal symmetry for the 66 pairs of hexiamonds.
