Description

Consider xylene:
CC1=C(C)C=CC=C1
image

ARC will attempt to calculate both rotors, where in fact it should identify that they are identical, and only run one of them.
(Beware of long-range interaction effects in larger species that are felt in 3D but not discoverable in 2D)

Research direction

Start by reproducing the xylene example in ARC and trace the rotor-calculation entry point that schedules both rotors. Determine how identical rotors are recognized per species while accounting for the stated long-range 3D interaction caveat. Done means equivalent rotors run only once without incorrectly merging rotors whose larger-species environments differ.
