Most teams have 2 wheels driving the robot forward and two driving it sideways, though some three wheel drives, with 2 driving forward and one driving sideways are commonly seen too. Though I haven't seen a robot in FIRST with triangular omnis, they can be found outside of FIRST. (Each wheel is mounted at the point of a triangle, and each is aimed 120 degrees to the others)

I believe The HOT team 67 did it in 2005, it wasnt actually having each wheel aimed at 120degrees but was arranged this way.
