There are 16 Distinct Systems of 16-Element Type Dichotomies in Socionics
Intro: Originally, I thought that the Reinin dichotomies and the Tencer-Minaev dichotomies were the only two systems of 16-element type dichotomies in Socionics. I just discovered another 14 systems, which is quite unexpected. I may even have been incorrect in my assertion that the Reinin dichotomies are the closest to Model A and Tencer-Minaev dichotomies are the closest to Model G, because there is simply far more to discover here. ... We saw that there were 35 possible partitions of 8 elements into two groups of 4 ( https://varlawend.blogspot.com/2023/06/encyclopedia-of-model-g-and-model.html?m=1) . nCr(8,4)/2 = 35 3 of those were temperament dichotomies that have a special structure in Socionics models, so there are a total of: 35 - 3 = 32 potential non-temperament dichotomies Based on the criteria of respecting the symmetries of the temperament dichotomies, we found out that 8 of them respect the symmetries. Since there are 4 non-temperament dichotomies in each 8-element dichotom
