ferrersDiagram -- a net of the Ferrers diagram

• Usage:

  ferrersDiagram(lam, mu)

  ferrersDiagram T

• Inputs:
  • lam, an instance of the type Partition, the outer shape $\lambda$.
  • mu, an instance of the type Partition, the inner shape $\mu$. If not given, if is assumed to be the $0$ partition.
  • T, an instance of the type YoungTableau, a skew tableau.
• Outputs:
  • n, a net, a representation of the Ferrers diagram of shape $\lambda/\mu$.

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