Enumerating Small Sudoku Puzzles in a First Abstract Algebra Course
Lorch, Crystal; Lorch, John
PRIMUS, v18 n2 p149-157 Mar 2008
Two methods are presented for counting small "essentially different" sudoku puzzles using elementary group theory: one method (due to Jarvis and Russell) uses Burnside's counting formula, while the other employs an invariant property of sudoku puzzles. Ideas are included for incorporating this material into an introductory abstract algebra course. (Contains 5 figures and 3 footnotes.)
