23 Enigma... thats all I can say... Specifically this part:
As with most numerological claims, the enigma can be viewed as an example of apophenia, selection bias, and confirmation bias. In interviews, Wilson acknowledged the self-fulfilling nature of the enigma, implying that the real value of the Laws of Fives and Twenty-threes lies in their demonstration of the mind's power to perceive "truth" in nearly anything.
2) Volnar was a Bajoran colony, not an "Expanse". Not to mention the logic of adding another exploration cluster that nobody would play (since all exploration clusters use the same missions and boring).
3) It doesn't conform to the Star Trek Star charts at all.
