QA-Px stands for some QA-point that is not registered in EQF.
Points indicated by *) are found by Eckart Schmidt. See Ref-34, QFG#1268.
 
Apart from the configuration where some Triple Triangles are Desmic with the QA-Component Triangles, there also is a situation where a set of 3 different Triple Triangles form a desmic configuration. Especially the desmic configuration of Triple Triangles QG-P2, QG-P8, QG-P15 is noteworthy as well as the desmic configuration of Triple Triangles QG-P1, QG-P18, QG-P19. Being desmic the triangles have to be mutually perspective. See Ref-34, QFG#2017.
