UKMT and the National Museum of Mathematics (MoMath) in New York, announced a joint competition to celebrate the discovery of the Hat Tile, an “Einstein” or aperiodic monotile, a shape which can tile the plane but can only do so non-periodically (in a non-repeating pattern).

Competition winners have now been selected – from the UK and internationally – and were awarded their prizes at the HAT Awards at The House of Commons on 12th December.  View the event highlights in the video below.
