comment Is there any way to generalize the Laplacian to finite groups?
Thank you for the recommendations. Terras' book looks promising.

comment Computer package for representation theory of the symmetric group
I'm writing modules in Haskell to do this sort of thing. See www.github.com/rotskoff. It won't be of use for this sort of question yet, but if other people have computations like examples (1) and (2) that they'd like to see implemented please let me know!

comment Which groups have strictly rational representations?
Artin's Theorem actually provides an explicit formula for the values of rational characters of a general group (see: Curtis and Reiner sect. 15) but I'm more interested in groups of the type F. Ladish mentions, i.e., those which are realizable over $\mathbb{Q}$

comment Partitions limit shape and LDP
I edited your question to reflect your correction. You should delete your answer when you get a chance. Also, very interesting question.
