ld) where l, is the length = A d-dimensional box is specified by a d-tuple B = (1, 2, of the box along axis j. It is possible to nest box B = (1,,d) inside box B2 (m1, m2, ma) if we can rotate the d-axes so that under the rotation B2 is wider than B along axes. I.e. if there exists a permutation on the d coordinates such that (1) < m1, ln(2) < m2, (d)
