## Basic properties

 sage: chi.conductor()  pari: znconreyconductor(g,chi) Conductor = 1021 sage: chi.multiplicative_order()  pari: charorder(g,chi) Order = 340 Real = No sage: chi.is_primitive()  pari: #znconreyconductor(g,chi)==1 \\ if not primitive returns [cond,factorization] Primitive = Yes sage: chi.is_odd()  pari: zncharisodd(g,chi) Parity = Odd Orbit label = 1021.v Orbit index = 22

## Galois orbit

sage: chi.sage_character().galois_orbit()

pari: order = charorder(g,chi)

pari: [ charpow(g,chi, k % order) | k <-[1..order-1], gcd(k,order)==1 ]
