2023-09-29 06:08:51 +0200	commented question	character table of normalizer It just seems inconsistent. Like G.conjugacy_classes_representatives() for G = CyclicPermutationGroup(4) and n.conjugacy

2023-09-28 08:41:51 +0200	marked best answer	Evaluating expressions with zetan for insertion into numpy array I'm working with the character table of the centralizer for Z4: `G = CyclicPermutationGroup(4)` followed by `t = G.character_table()` yields `[ 1 1 1 1] [ 1 -1 1 -1] [ 1 -zeta4 -1 zeta4] [ 1 zeta4 -1 -zeta4]` I'm trying to simplify results of calculations using this table for insertion into numpy arrays (these results simply involve adding and multiplying elements of the table). For example, let us consider `f = t[1,3] - 4 * t[3,3]` which evaluates to `-4*zeta4 - 1`. I've tried using `AlgebraicConverter` and `.arithmetic()` functionalities. `a = AlgebraicConverter(QQbar) a.arithmetic(f, f.operator())` I obtain the following error `AttributeError: 'sage.rings.number_field.number_field_element.NumberFieldElement_absolute' object has no attribute 'operator'` Advice on how to remedy this error or how to follow a better approach would be greatly appreciated.
