If lower is False then the strictly lower triangular part of each inner-most matrix is assumed to be zero and not accessed. The value of the element in the matrix has to be 0. Slightly more general, let F* be an arbitrary flag in a vector space V with dim(V) = n. So we have with dim( £ ) = r. The corresponding nilalgebra is defined by
