# Minimal Convex Polyiamond Tilings

Given a polyiamond, how few copies of it can be joined to form a convex
shape?
Such a shape must be a triangle, quadrilateral, pentagon, or hexagon.
Here I show minimal known convex tilings for polyiamonds with up through
9 cells. If you find a smaller solution or solve an unsolved case,
please write.

At Math Magic for
April 1999,
Erich Friedman considers for various plane shapes
the set of values of *n* for which *n* copies of the shape
can form a convex shape.
Ed Pegg Jr. also considers this problem at Dissections of Convex
Figures.

from Pairs of Polyiamonds.
