Dear all First of all it is difficult to comment a solution which is not presented but just referred to. I assume that this unknown suggested solution is as follows:
Assume a master and an apprentice: An actor can be the only member of a singleton group. The relationship master.-apprentice can be expressed as a group having the master-singleton and the apprentice-singleton as members. The type of the singleton-group can express the relation the members have in the master-apprentice group. If this is the solution it is of course possible but very artificial like epicycle models of the planet orbits. I may be blind, but I dont find any sub group property in the model.
