I made a slight error - it would require three dichotomies, since there are four dimensional categories. It's fairly easy if you just look at which dichotomies, say, the 1st and the 8th share. Mental/vital is out, as is valued/non-valued. It just so happens that the two unnamed dichotomies combine with the strength dichotomy to make dimensionality.
1368 / 2457
-corresponds with homeoversion/heteroversion (with respect to the base function).
1458 / 2367
-I might call this one central/peripheral (any better ideas?). Central are the dominant elements of one's Identical, Conflictor, Dual, and Quasi-Identical.
4 strong, homeoverted, central
3 strong, heteroverted, peripheral
2 weak, homeoverted, peripheral
1 weak, heteroverted, central
1 - base, four-dimensional
2 - creative, three-dimensional
3 - normative, two-dimensional
4 - painful, one-dimensional
5 - suggestive one-dimensional
6 - activation, two-dimensional
7 - program, three-dimensional
8 - instrument, four-dimensional
