YoungTableau -- a type of HashTable representing a (nonskew) Young tableau

Description

This is a subclass of SkewTableau. Each object of YoungTableau is essentially just a skew tableau with inner shape $\mu=0$.

i1 : lam = new Partition from {4,3,2}

o1 = Partition{4, 3, 2}

o1 : Partition
 
i2 : entryList = toList(1..(sum toList lam))

o2 = {1, 2, 3, 4, 5, 6, 7, 8, 9}

o2 : List
 
i3 : T = youngTableau(lam,entryList)
