Definition

This is the unique field (up to isomorphism) having eight elements. It is denoted $F_{8}$ or $G F (8)$ . It can be defined as:

$F_{2} [x] / (x^{3} + x + 1)$ .

where $F_{2}$ is the field of two elements.

additive group	elementary abelian group:E8	(8,5)
multiplicative group	cyclic group:Z7	(7,1)
general affine group of degree one	general affine group:GA(1,8)	(56,11)
projective special linear group of degree two	projective special linear group:PSL(3,2)	(168,42)

The field can be defined using GAP's GF function:
