Tiling a Chamfered Rectangle with Three Pentaboloes

Introduction

A pentabolo or pentatan is a plane figure formed by joining five equal isosceles right triangles at their legs or hypotenuses. Here are the 30 pentaboloes:

A chamfered rectangle is a rectangular polyabolo with its corner cells clipped diagonally. To prevent cuts from meeting, I require the dimensions of the rectangle to be 3 or greater.

Here are chamfered rectangles tiled with copies of three different pentaboloes. There are 4,060 sets of three pentaboloes, too many to show here. Instead I show the minimal known tilings that have at least 150 tiles.
