The Logicians were a baseball team formed by Captain Solok, and members of the all Vulcan crew of the USS T'Kumbra. Their team logo featured the Vulcan IDIC symbol.

In 2375, the Logicians challenged Captain Benjamin Sisko's team, the Niners – a team representing Deep Space 9. The Vulcans' superior physical abilities ensured their victory, but they failed to appreciate that winning was not nearly as important as enjoying the game. (DS9: "Take Me Out to the Holosuite")
