You might want to add the Inter-Stellar Concordium to the list of major Alpha Octant empires* there; plus the Lyrans and Hydrans are no less major than the Gorns or Kzintis would be.
And to be fair to the (Neo-)Tholians and Seltorians, they do (or in the case of the Tholians, did) run an entire galaxy; it's only the various forces that made it from M81 to the Milky Way that one could consider "minor".
Plus there's a whole bunch of other empires in various non-Alpha settings; but they will have to wait for quite a while, I imagine.
*These days, ADB prefers to use "empire" or "species" (whichever term is more appropriate to the situation) rather than "race".
