## The Rectangular Spiral Solution for the n_1 X n_2 X … X n_k Points Problem

**Authors:** Marco Ripà

A generalization of Ripà’s square spiral solution for the nXnX…X n points upper bound problem. Additionally, we provide a non-trivial lower bound for the k-dimensional n_1Xn_2X…Xn_k points problem. In this way, we can build a range in which, with certainty, all the best possible solutions to the problem we are considering will fall. Finally, we provide a few characteristic numerical examples in order to appreciate the fineness of the result arising from the particular approach we have chosen.
