By the way, Mongia did not generate the tables, he referenced them from articles by Levi, Crystal and Young, and Toulios and Todd. All of this work was done before 1965, what were you doing back then? The solutions are "cumbersome" according to Mongia, and won't be attempted here. Nowadays you can obtain the solutions using an optimizer, like we did in the final example below.
