By the way, strictly speaking the marks around the outside of the magic disk represent elements of the projective plane of F2, not elements of F2 x F2 x F2. However, since the only elements of F2 are 0 and 1, there is only one representation for a given ratio (or set of ratios) of values; and so the projective nspace Pn(F2) is pointforpoint identical to the vector space (F2)^(n+1) with the origin excluded (for any n>0). This is not true for any other finite group Fp, p>2.
