I was in hope that you understand while writing a related article that the transistor you are talking about cannot really exist There is no problem to build a transistor with more than Emitter or with more than one Collector and in fact these transistor variants really exist A multibasis transistor would be a transistor with one Emitter one Collector and more than one Basis I cannot imagine how this should be made It is thus more likely that people use eg two transistors in a specific way that would allow to compensate the noise This is how the basic idea for the bipolar transistor has been discovered by Herbert Matar in  while he was working on a Duodiode that should allow to compensate the noise in a mixer for a  GHz Radar receiver And BTW talking about rules in general such a discussion belongs to the talk page of the transistor article
