Fano Plane - Steiner System

Steiner System

The Fano plane, as a block design, is a Steiner triple system. As such, it can be given the structure of a quasigroup. This quasigroup coincides with the multiplicative structure defined by the unit octonions e1, e2, ..., e7 (omitting 1) if the signs of the octonion products are ignored (Baez 2002).

Famous quotes containing the words steiner and/or system:

    The variables are surprisingly few.... One can whip or be whipped; one can eat excrement or quaff urine; mouth and private part can be meet in this or that commerce. After which there is the gray of morning and the sour knowledge that things have remained fairly generally the same since man first met goat and woman.
    —George Steiner (b. 1929)

    The genius of any slave system is found in the dynamics which isolate slaves from each other, obscure the reality of a common condition, and make united rebellion against the oppressor inconceivable.
    Andrea Dworkin (b. 1946)
