Shortcut back to Sextillions Special solutions: Sextillions



The solutions below were sent to us by Jack Wetterer, associate professor of physics at the US Air Force Academy and a big fan of polyomino and polycube sets. Professor Wetterer liked the way we package Heptominoes as a three-part rectangle and worked out a couple of three-rectangle divisions for Sextillions. Notice that the middle ones have a hole that's the shape of one of the pieces.

Jack also liked our star-shape design for Poly-5 and built an even larger one with the combined sets, with co-solver Chris Patterson. Enjoy!

Three 6x12 rectangles, with the 11 unequal pieces all together in the center enclosing a hole like one of their own. Three 9x8 rectangles, with a symmetrical center hole. A PolyStar with the combined Poly-5 and Sextillions set, going outward from smallest to largest.

Later, Jack sent us these two rectangular solutions that allow division of the Sextillions set into 3 subrectangles, with the 12 "unequal" pieces all contained in one group. Jack custom-ordered these in the color divisions you see here, to match the style of his Heptominoes and Octominoes.
