Preliminaries
A total of 53 teams entered the competition and were divided into seven preliminary groups of seven or eight teams each. The top two from each group advanced to Final A, the teams placed third-fourth to Final B, no. 5-6 to Final C, and the rest to Final D. Preliminary head-to-head results were carried over to the finals, so no teams met more than once. All preliminary groups and finals were played as round-robin tournaments. The results were as follows:
