(Added May 1, 2013: This puzzle raffle is now closed. Many thanks to all who participated. Here’s a solution.)
Last month, Girls’ Angle affiliates Rediet Abebe, Jordan Downey, and Lauren McGough hosted a mathophile raffle contest at the Girls’ Angle booth in the 2013 FIRST Robotics Career Expo in New York City. Nobody succeeded in solving the first question on that raffle, so we’re reposting it here. To enter, please send your name, solution, and contact info to girlsanglepuzzler “at” gmail.com by April 30, 2013. We will draw randomly from the correct entries received and the winner will receive some chocolate from L. A. Burdick. For this one, if you have a doctoral degree in mathematics, you’re not eligible for the prize.
The menu of links above is taken from former Girls’ Angle mentor, now graduate student at the University of California, Berkeley, Maria Monks’ website.
How many ways can the link titles be placed into the squares (one per square) so that they are in alphabetical order down any column and across any row (going from left to right)? (Note: Her current layout does not obey this property. Also, “Home” is not required to go in the upper left square.)
(We will not use your contact information for any purpose other than to deliver your prize, should you win. After the winner has been selected, all emails received will be promptly deleted. At the winner’s discretion, we will let you know who won. Anyone who makes more than one submission will be disqualified! Sorry! Also, this offer is only valid in those states in the United States where such things are legal. There is no fee to enter this puzzle contest.)
