The eight eighthfinal winners advance to the quarterfinals.

The eight eighthfinal losers continue their participation in the playoffs for the distribution of the places from ninth to 16^th.

The bottom two teams in the final standings of each pool continue their participation in the playoffs for the distribution of the places from 17th to 24th.
