Pento-Pento-Trominoes

Given one tromino and two pentominoes, can we find a polyomino that each of them can tile? This page was inspired by Livio Zucca's Pento-Tetro-Trominoes.

If you find a smaller solution or solve an unsolved case, please write.

The Master At Work

Almost as soon as this page appeared, Livio Zucca was the first to solve 5I-5Z-3L by joining three copies of a solution for 5I-5Z:

Smaller solutions have since been found; see the table below.
