Thanks! I've used \{ and \} successfully in the past, but it must have been in the comments.

So I really should have ordered the list in the more fun manner of N-U-T. As far as I know, there is no use made of the ordering of this trichotomy in the study of spherical varieties, at least not explicitly.

@darij grinberg: Only using simple transpositions defines the weak order on S_n, while using all transpositions defines the Bruhat order.

You might start with Seshadri's "Standard Monomial Theory -- A Historical Account" (in volume 2 of his collected works) or Lakshmibai/Littelmann/Magyar's "Standard Monomial Theory and Applications" (available online).

I don't see any reason that you should close this suggestion thread or those on other sites when MoMath opens. Presumably, even after the first exhibits go up you'll be changing the exhibits from time to time and occasionally want to design new ones.

Also if you post the question on Math stackexchange, you should state what definition of Chern class you are using.

This is a perfectly reasonable question, but not for this site. The best place for this question is math.stackexchange.com

I don't have anything insightful to say regarding the problem, but I always thouht that the 1x3 pieces were the submarine and the destroyer, and the 1x2 piece was a PT boat.
