Charles Coffin Sims (born April 14, 1937 in Elkhart , Indiana , † October 23, 2017 in Saint Petersburg , Florida ) was an American mathematician who studied finite groups .

Sims received his PhD from Harvard University in 1963 with John Griggs Thompson (Enumeration of p-groups). He taught as a professor at Rutgers University , where he had been since 1965. From 1982 to 1984 he was chairman of the mathematics faculty there. In 2007 he retired and lived in Saint Petersburg (Florida).

Sims was a pioneer in algorithmic group theory, where he is known among other things for the Schreier-Sims algorithm (named after him and Otto Schreier ) from 1970. Together with Donald G. Higman, he discovered the Higman Sims group, a sporadic group , and using the permutation group software he had developed, he proved the existence of further sporadic groups, the Lyons group ( assumed by Richard Lyons 1970) and the O ' Nan group ( assumed by Michael O'Nan in 1976), both of which are sometimes also named after Sims. With Jeffrey Leon he constructed the baby monster group .

He was a fellow of the American Mathematical Society . In 1969 he received a research grant from the Alfred P. Sloan Foundation ( Sloan Research Fellowship ).
