grpdgrp

grpdgrp
is an internal variable saving the used standard representation.

DetailsDetails

  • grpdgrp takes the following values:
    grpdgrp = 1, the standard representation is O(3).
    grpdgrp = 2, the standard representation is SU(2).
    grpdgrp = 3, the standard representation is O(2).
    grpdgrp = 4, the standard representation is given by permutation matrices.
    grpdgrp = 5, the standard representation is SU(2)x{-1,1} ("SU(2)xS").
  • Use GTChangeRepresentation to change the value of grpdgrp.
  • Use GTWhichRepresentation to read the value of grpdgrp.
