Octiamond Oddities

An octiamond oddity is a figure with binary symmetry formed by an odd number of copies of a octiamond. Here are the minimal known oddities for octiamonds. Please write if you find a smaller solution or solve an unsolved case. Mike Reid contributed improvements to some of these solutions.
