The Australian Mathematical Society Gazettes Puzzle Corner is a regular column with entertaining mathematical puzzles, here’s an example: "Garden gnomes Jack positions nine garden gnomes in such a way that ten distinct straight lines are formed, each containing three gnomes. Jill thinks the arrangement is taking up too much space and moves two gnomes to new locations. Jack notices that even though the new configuration is more compact, it still contains ten distinct lines of three. How is this possible?" You can find the Puzzle Corner, as well as the entire Gazette online at: http://www.austms.org.au/Gazette+Volume+38+Number+3+July+2011 Please check it out when you feel like trying out random fun problems, and be sure to send your solutions to us.
