The Lie algebra splitg2 with Mathematica using Zorn's matrices
  We will obtain in this paper a generic expression of any element in athe Lie algebra of the derivations of the split octonions a over an arbitrary field. For this purpose, we will use the Zorn's matrices. We will also compute the multiplication table of this Lie algebra.
