Other Sizes - Part 4 of The Mathematics of Professor Alan's Puzzle SquareAlan Dix
The basic version of the puzzle square consists of 16 tiles in a 4x4 grid. However, you can have any size. In this third part of The Mathematics of Professor Alan's Puzzle Square, we see how some of the things we learnt about the standard square generalise to different sizes ... and also one crucial thing that doesn't.
