  • Graphs representing the Cartan matrix of the monoid of upper unitriangular boolean nxn matrices. For the second one, I can't resist quoting Tom Denton: "First they tell us we will never need more than 640k of RAM, then they tell us our documents should always be less than the length of a limousine..."

  • The J-order on the BiHecke monoid for the symmetric group S_3

  • Sage-Combinat T-Shirt for FPSAC 2009:
