It can be proven easily that CAS and RAS wave functions are special cases of GAS, with one and three active spaces, respectively. We trivially note that in CAS, as only one active space is necessary, a single supergroup is generated. We also note that GAS wave functions with purely disconnected spaces have also one supergroup, with a constant number of electrons per GAS space. On the contrary, the electronic configurations generated in RAS wave functions, can already be distributed among a number of supergroups, depending of the level of excitation from RAS1 and into RAS3 spaces.
