Michael J. T. Guy (born 1 April 1943[citation needed]) is a British computer scientist and mathematician.
[2][3] Also with Conway, an enumeration led to the discovery of the grand antiprism, an unusual uniform polychoron in four dimensions.
It was through Michael that Conway met Richard Guy, who would become a co-author of works in combinatorial game theory.
[7] He did not complete a Ph.D., but joint work with Cassels produced numerical examples on the Hasse principle for cubic surfaces.
He worked on the filing system for Titan, Cambridge's Atlas 2,[9][10] being one of a team of four in one office including Roger Needham.
