class property galois.FieldArray.primitive_elements : FieldArray

All primitive elements \(\alpha\) of the Galois field \(\mathrm{GF}(p^m)\). A primitive element is a multiplicative generator of the field, such that \(\mathrm{GF}(p^m) = \{0, 1, \alpha, \alpha^2, \dots, \alpha^{p^m - 2}\}\).

Examples

All primitive elements of the prime field \(\mathrm{GF}(31)\) in increasing order.
