We study a particular geometry in characteristic 2. Let X be a cubic surface obtained from ℙ2 by means of blowing up with centersP1,...,P6. We prove that X is projectively equivalent to the Fermat cubic surface with equation ∑xi3 if and only if each point of P1,..., P6 is the nucleus of the conic passing through the remaining five points.
