An S3-symmetric Littlewood-Richardson rule
Abstract
The classical Littlewood-Richardson coefficients C(lambda,mu,nu) carry a natural S3 symmetry via permutation of the indices. Our "carton rule" for computing these numbers transparently and uniformly explains these six symmetries; previously formulated Littlewood-Richardson rules manifest at most three of the six.
