MutableYoungTableau _ Sequence = Thing -- change an entry of a mutable Young tableau

• Operator: _

• Usage:

  T_thePosition = k

• Inputs:
  • T, an instance of the type MutableYoungTableau, a mutable tableau.
  • thePosition, a sequence, a pair (i,j) of integers.
  • k, a thing, the new entry in position (i,j).
• Outputs:
  • T, an instance of the type MutableYoungTableau, a mutable tableau with entry k in position (i,j).

i1 : T = mutableYoungTableau(new Partition from {4,2,1}, new Partition from {1}, toList(1..6))
