To download the package Zorn.m click : here
This package implements the product in Zorn matrix algebra, its norm and standard involution. It also creates a standard basis formed by two orthogonal idempotents whose sum is 1, three elements in one Peirce subspace and other three in the suplementary Peirce subspace. This package is related to the following one: g2

Computes the form of a general derivation of Zorn's Matrices algebra C. From here a basis of g2=Der(C) can be computed. It includes the bracket x.y-y.x of two elements x and y in the derivation algegra g2 of C. It computes a Cartan subalgebra of g2 as well as a generator in each root space. Finally it computes a maximal Torus in G2=Aut(C).

This implements a "standard" basis in the Albert algebra A=H_3(C,*) where C is as in the above package and computes product, the quadratic U-operator and other features. It gives any element in A as a formal linear combination of elements in the standard basis (also its TeXForm). It gives also the coordinates of elements relative to the mentioned basis and calculates a maximal torus in the automorphism group F4 of Albert's algebra.

It gives the general form of an element in the derivation algebra f4 of the Albert algebra A. We compute a maximal torus in aut(A) and the Weyl group W[[1]]....W[[1152]] of f4 and finds a system of elements in the normalizer of the maximal torus of aut(A) whose projections in the Weyl group is the set of elements W[[1]]......W[[1152]]. It finds a maximal torus in aut(f4) as well as a root system of f4.

This provides certain utilities the main being the computation of a basis from a generic element (with parameters) in any linear vector space .
