(2017) as the analogue of the classical PLR group. While the PLR group connects triadic cadential sets via the relative morphism $R$, the tetradic case reveals a richer structure: two pairs of cadential sets connected by distinct morphisms forming a ``prism'' in the coslice category over the common chords of the paired cadential sets, and a single pair for those that allow quantized modulations.
