Tetrapent Triplet Oddities

Introduction

An oddity is a figure with binary symmetry formed by an odd number of copies of a polyform.

Oddities can also be constructed from sets of different shapes. Here are the minimal known oddities for triplets of tetrapents, using at least one copy of each tetrapent. Please write if you find a smaller solution or solve an unsolved case.
