Note that the acronym here was chosen to be "tutrippapy" for this tutrip pyramid. In contrast, "tutrippy" then refers to the external 2 trippy blend instead. Nonetheless this polychoron can likewise be considered an internal 2 trippy blend as well. In fact, in here one trip each blends into a tutrip, whereas in the external one a squippy each would blend into an oct.
