In the Pigeonhole Principle Sweatshirt you can be as comfortable as the pigeons are in their pigeonholes. Featuring five pigeonholes and seven pigeons! Since there are more pigeons than there are holes, it's no surprise that the Bernoullis had to squish themselves in together. The pigeons are (clockwise) Euclid, Fermat, Gauss, and Euler, and in the center are the Bernoullis (Johann, Jacob, and Daniel). With the soft fleece inside and comfortable fit, it’s sure to become your favorite study sweater right away!
