FiniteFieldIndex

FiniteFieldIndex[u] gives the index of the FiniteFieldElement object u.

Examples

Get the index of a finite field element:

ff = FiniteField[2, 3];
a = ff["PrimitiveElement"];
FiniteFieldIndex[a]

Get indices for powers of the primitive element:

Table[FiniteFieldIndex[a^k], {k, 0, 6}]
