In the August Word Ways I challenged readers to find the smallest rectangle in which one can pack the 37 different US presidential surnames with at least one name in each of the eight possible directions (but connectivity not required). My answer to this challenge is shown below, an 18x12 = 216 rectangle in which FILLMORE does not connect to nay other; each diagonal direction has a single representative.
