Abstract
We study a particular geometry in characteristic 2. Let X be a cubic surface obtained from bP2by means of blowing up with centers P_{1} , ldots, P_{6} . We prove that X is projectively equivalent to the Fermat cubic surface with equation Sigma x_{i}^{3}= 0if and only if each point of P_{1} , ldots, P_{6} is the nucleus of the conic passing through the remaining five points.
