Laderman matrix multiplication algorithm can be constructed using Strassen algorithm and related tensor's isotropies
In 1969, V. Strassen improves the classical 2x2 matrix multiplication algorithm. The current upper bound for 3x3 matrix multiplication was reached by J.B. Laderman in 1976. This note presents a geometric relationship between Strassen and Laderman algorithms. By doing so, we retrieve a geometric formulation of results very similar to those presented by O. Sykora in 1977.
