Holeless Pentomino Odd Pairs

Introduction

Livio Zucca's Pentomino Odd Pairs studies the problem of finding a compatibility figure for two pentominoes with an odd number of tiles. Here I show holeless variants for pentomino odd pairs. The green cells represent holeless solutions that already appear on Pentomino Odd Pairs.
