allTabloids -- list all tabloids of a given shape

Usage:

allSemistandardTableaux(lam,mu)
Inputs:
- lam, an instance of the type Partition, the outer shape, $\lambda$.
- mu, an instance of the type Partition, the inner shape, $\mu$.
Outputs:
- b, a bag, bagged list of all tabloids of given shape and entries in $\{1,\ldots,N\}$, where $N$ is the size of the tabloid.

Description

i1 : theBag = allTabloids(new Partition from {4,3,1})

o1 = -*a bagged sequence of length 280*-

o1 : Bag

i2 : for i from 0 to 4 do print theBag#i
