Dear Joe, Illustrator files. If you sent an eps file to Chris Beaumont ([email protected]) he can convert it into an Adobe Illustrator I've put the final version of the t-shirt design on my web page, again at http://shimura.math.berkeley.edu/~was/hottopics There is a link to the postscript file, which Chris should be able to convert using Adobe Illustrator. If we have at least 50 shirts (not a bad idea; I suspect that we I think we need at least 60 shirt, since I'm going to take 8 of them (for my mom, my grandma, Helena, my brother, and for Ezra who drew the icosahedron). come to about $11 per shirt, which seems reasonable to me. Yep, I agree. How seriously do we need all of the colors in the X_0(243) diagram? Would black suffice? Or a single color? There are eight lines in the diagram. Two correspond to elliptic curves, two to surfaces, two to three-folds, and two to oldforms. I colored them in pairs red, blue, black, and purplish (the same as the icosahedrom), respectively. Thus the t-shirt now contains a total of four colors (including black) and the color scheme of the lines is systematic. I suppose that Hecke should really be listed in the Artin conjecture list (dihedral representations), but the list is long already. OK. Done. William
