I expected a character table from
g=Zmod(5).unit_group()
g.character_table()instead I got an error message ending with
AttributeError: 'AbelianGroupWithValues_class_with_category' object has no attribute 'character_table'How do I create the character table of the group of units mod n ?
You can use gap
sage: g=Zmod(5).unit_group()
sage: g_gap = gap(g)
sage: char = gap.CharacterTable(g_gap)
sage: irr = gap.Irr(char)
sage: gap.Display(irr)
[ [ 1, 1, 1, 1 ],
[ 1, -1, 1, -1 ],
[ 1, E(4), -1, -E(4) ],
[ 1, -E(4), -1, E(4) ] ]See https://trac.sagemath.org/ticket/19329 for a followup that was never implemented to a similar question.
