Help needed in pre-colloquium build
We need a few students to help build the object shown below. This object (which I’m sure we will learn the name of during the colloquium) will be used in the colloquium on symmetry (details below). We will start the build at 2:00 PM on Tuesday, February 5 in the lobby outside the lecture halls on the first floor of VanderWerf. The build will probably last until around 4:00 PM. If you can’t come at the beginning, you are still welcomed to help when you can. As a bonus you can earn a colloquium credit for helping build!

Problem of the Fortnight
A 3 × 3 magic square is a grid of distinct numbers whose rows, columns, and diagonals all add to the same integer sum. Sunnie creates a magic square whose sum is N, but her keyboard is broken so that when she types a number, one of the digits (0−9) always appears as a different digit (e.g. if the digit 8 always appears as 5, the number 18 will appear as 15).
The altered square is shown below. Find N.
Write up your solution (not just the answer) and drop in the Problem of the Fortnight slot outside Professor Mark Pearson’s office (room 212 in The Werf) by 3:00 p.m. on Friday, February 8. As always, be sure to include your name and the name(s) of your math professor(s) — e.g. David Copperfield, Professors Penn and Teller– on your solution. Good luck and have fun!
