class property galois.FieldArray.characteristic : int

The prime characteristic \(p\) of the Galois field \(\mathrm{GF}(p^m)\). Adding \(p\) copies of any element will always result in 0.

Examples

In [1]: galois.GF(2).characteristic
Out[1]: 2

In [2]: galois.GF(2**8).characteristic
Out[2]: 2

In [3]: galois.GF(31).characteristic
Out[3]: 31

In [4]: galois.GF(7**5).characteristic
Out[4]: 7
