#17338: Fix printing of Dirichlet characters
-----------------------------+----------------------------------------
Reporter: pbruin | Owner:
Type: defect | Status: new
Priority: minor | Milestone: sage-6.4
Component: number theory | Keywords: Dirichlet characters

-----------------------------+----------------------------------------
Dirichlet characters modulo 2 are printed in a strange way:
{{{
sage: DirichletGroup(2)[0]
Dirichlet character modulo 2 of conductor 1 mapping
}}}
After #17337, this also happens for Dirichlet characters modulo 1.
This ticket makes Dirichlet characters modulo 1 and 2 print as
{{{
sage: DirichletGroup(1)[0]
Dirichlet character modulo 1 of conductor 1
sage: DirichletGroup(2)[0]
Dirichlet character modulo 2 of conductor 1
}}}
and uses the `mapping ...` only for conductors >= 3:
{{{
sage: DirichletGroup(3)[1]
Dirichlet character modulo 3 of conductor 1 mapping 2 |--> -1
}}}
