What are the Omaha Hi-Lo hand rankings and how do they determine the winning hand in this poker variant?

In Omaha Hi-Lo, the hand rankings are the same as in regular Poker. The winning hand is determined by the best high hand and the best low hand, with the pot split between the two. The high hand rankings are the same as in regular poker, while the low hand must have five cards ranked 8 or lower, with no pairs or better. The best low hand is A-2-3-4-5, also known as the "wheel."
