This week’s SUMS talk is being given by USyd alum David Gruenewald. Abstract: In this talk I will define what a nxn magic square is (n>0 an integer) and provide methods of producing one. It turns out to be simplest to produce an nxn magic square when n is odd. Next easiest are n=4k and then n=4k+2. I provide methods for all the cases. Time permitting I’ll show you some other cool things about magic squares and a "mathematical" construction of nxn magic squares (where n is odd) that involves latin squares (to be defined; a solved sudoku puzzle is a special case of a latin square but this talk will have nothing to do with sudokus!)
