Triangular Enneiamond Compatibility

Introduction

The triangular enneiamond is a polyiamond made of nine equal equilateral triangles joined to form a bigger triangle.

The compatibility problem is to find a figure that can be tiled with each of a set of polyforms. Here I show minimal known compatibility figures for the triangular enneiamond with other polyiamonds. If you find a smaller solution or solve an unsolved case, please let me know.
