The Four Cubes Problem - 2

4 cubes with 4 colours across their 6 faces, 82,944 possible ways of stacking them - how do we stack them to have all four colours on each side of the stack? This is the problem of Instant Insanity, to which there are two distinct methods of solution. Robin Wilson, Gresham Professor of Geometry, here explains how to solve it by associating the colours with different prime numbers. This is the 24th part of 'A Millennium of Mathematical Puzzles'. The full lecture is available (in 24 parts) here on YouTube, or it can be downloaded (like all of our lectures) in its complete form from the Gresham College website, in video, audio or text formats: http://www.gresham.ac.uk Gresham College has been giving free public lectures since 1597. This tradition continues today with all of our five or so public lectures a week being made available for free download from our website.
