With the first two rounds finished for this tournament, only 16 teams remain in the Sweet 16. These 16 are divided into 4 regions, of which one team will come out of each one in the Final Four. What will be the total number of these four teams' seeds?

For reference, the lowest # can be 7 (assuming the highest-seeded teams of each region make it), and the highest # can be 37 (assuming the lowest-seeded teams of each region makes it).

This market will be closed before the start of the Elite 8 matches and will be resolved soon after all four Elite 8 matches are completed.

The seeding of these regions is as follows (italicized for eliminated teams):
