Problem of the Week

for Tuesday, September 23, 2014

Hexagonal polyominoes are formed by joining congruent hexagons together along a common edge. The three different kinds composed of 3 hexagons are pictured below. Draw all the different hexagonal polyominoes that can be formed with 4 hexagons. Note that two hexagonal polyominoes are considered the same if there exists any combination of sliding, spinning, or flipping motions that can make one shape align perfectly with the other.
