CALLING SEQUENCE:

Diagonal2Part(diago)

PART[Diagonal2Part](diago)

PARAMETERS:

SYNOPSIS:

• The Diagonal2Part function takes a list [v,pos] as argument, where v is a list (lengths of the successive diagonals of the diagram of part) and pos an integer (position of the main diagonal), and returns the partition part such that Part2Diagonal(part) = [v,pos].

• Whenever there is a conflict between the function name Diagonal2Part and another name used in the same session, use the long form PART['Diagonal2Part'].
