QA-Tr-2: (Quadri-)Perspective QA-Triple Triangles

Below are combinations of Triple Triangles that exhibit a (Quadri-)Perspective relationship, along with their corresponding perspector. The Triple Triangles are defined by QG-, QL-, and QA-points, which generate the configurations within the QA or QL environment.

QA-Px stands for some QA-point that is not registered in EQF.

Points indicated by *) are found by Eckart Schmidt. See [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 [34], QFG#2017.
