How few similar (scaled) copies of a given polyabolo can form a convex shape? For most polyaboloes, the tilings with the fewest tiles use equal tiles, as with this triabolo:
Here I show the only polyaboloes I know of for which the convex tiling with the fewest tiles uses tiles of different sizes. If you find another such polyabolo, or a tiling with fewer tiles than shown, please write.
