Eighteenth century Swiss mathematician Leonard Euler was prolific in every sense. He fathered 13 children and probably just as many branches of mathematics. One of his many legacies is the name "Latin square" to describe a matrix in which each row and column forms a permutation of the numbers 1,2,3,...,n. He was the original Sudoku addict! Like Euler, Ian Wanless discovered that playing with Latin squares is fun a long time before it became fashionable. In this colloquium he will explain some of his recent extensions of Euler's fundamental discoveries.

Each Sudoku has a unique solution that can be reached logically without guessing. Enter digits from 1 to 9 into the blank spaces. Every row must contain one of each digit. So must every column, as must every 3x3 square. Educational narky Tue, 12 Dec 2006 11:07:58 GMT
