Monomials in k[x,x2 xr) correspond to Franklin squares under this map, and
multiplication of monomials conesponds to addition of Fianklin squaies. Foi example, the monomial AJAJ00 corresponds to the Franklin square 5/21 -F 200/23. Different combinations of Hilbert basis elements that give rise to the same Franklin square can then be represented as polynomial equations. Thus, from the two different Hilbert basis constructions of F2 represented in Figures 12 and 13, we learn that
