## Basic properties

 sage: chi.conductor()  pari: znconreyconductor(g,chi) Conductor = 4001 sage: chi.multiplicative_order()  pari: charorder(g,chi) Order = 20 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 = Even Orbit label = 4001.h Orbit index = 8

## 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 ]
