Magic squares have fascinated mathematicians for centuries, anddevelopments in the theory are still being made. Developed in China25 centuries ago, a magic square is an n x n array of distinctintegers such that each row, column, and main diagonal have the samesum. At the age of 85, Dame Kathleen Ollerenshaw has extended the limits ofthe subject.
