All of the matrices comes from choosing different bases for the underlying irreducible module. The surface differences are specht - Specht's representation, all of the entries are integer orthogonal - Young's orthogonal form, matrices are orthogonal seminormal - Young's seminormal form, a "scaled version" of the orthogonal form in which all entries are rational --Mike -- -- To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org
