In a weekend basketball tournament, three preliminary matches are played on Saturday: Team E vs Team F, Team G vs Team H, and Team I vs Team J, with no possibility of ties. Each winner from these matches qualifies for a semi-final round on the same day. The semi-final pairings are such that the winner of the first match plays the winner of the second match, and the third match winner plays against a pre-selected challenging team, Team K. On Sunday, the winners from these semi-finals play for first and second places, while the losers play for third and fourth places. Assuming Team K is also a winner from its Saturday match, determine the total number of possible four-team ranking sequences at the end of the tournament.
