Strictly proper 7-tone 31edo scales

This is a list of 7-tone scales in 31edo which are strictly proper with regard to the Rothenberg propriety.

The "type" of a scale is defined by the linear temperament supported by 31edo in which it has the least span. "Breed type" means it is a tie between miracle and hemiwuerschmidt.
