Produce tables of Dirichlet characters. A Dirichlet character

χ

modulo

m

is a multiplicative function that satisfies:

1.

χ(n)

is periodic with period

m

.

2.

χ(n)

is zero when

n

is not coprime to

m

.

3.

χ(n)

is an

th

m

root of unity when

n

is relatively prime to

m

.

4. There are

ϕ(m)

Dirichlet characters for a given

m

.
