When the guy on the 600 Club first says that they've discovered a new planet, he says it's in the "Alpha Ceti Six" system.
I wonder if this is supposed to be a play on ST:TWOK. Kahn was marooned on "Ceti Alpha Five", and the crew of the Reliant (Chekov and Capt Terrell) thought they were on Ceti Alpha 6.
Just a thought..........
