SkewTableau _ Sequence -- get the entry at a specific position.

Operator: _
Usage:

T_seq

T_(i,j)
Inputs:
- T, an instance of the type SkewTableau, a tableau.
- seq, a sequence, a pair (i,j) of integers in ZZ.
Outputs:
- theBox, a thing, the entry of T in position (i,j).

Description

The notations (T^i)#j, (T_j)#i, and T_(i,j) are all equivalent for valid positions (i,j). However, the notation T_(i,j) will raise an error for nonvalid positions, whereas the other two will return null.

i1 : T = skewTableau(new Partition from {4,3,1,0}, new Partition from {1,1}, {1,2,3,4,5,6})

o1 : SkewTableau

i2 : (T^0)#1

o2 = 1

i3 : (T_1)#0

o3 = 1

i4 : T_(0,1)

o4 = 1
