M Theory Lesson 79

Event Symmetry has also long pondered the j-invariant, and now has a post relating this invariant to a hyperdeterminant of type 4, which is to say a function of a 2x2x2x2 hypermatrix. He points out that the degree of the polynomial is the magical number 24, the dimension of the Leech lattice. Note that Michael Rios has also been keen on hyperdeterminants for some time because of their appearance in the quantum computational approach to Black Hole entropy.
