As an introduction to this section, the chapter on tri-sect Mitchell movements is recommended. This movement is useful for premises where there is not one large room. There may be several floors or several large rooms to be used. These rooms, however, may not always be of the same size. This movement allows for three groups of tables ranging from 3:4:4 up to 8:8:8 except that there cannot be more than one three table section.
Each section plays 4 rounds (as a separate movement) before there is any major movement between sections. In each section there are only 4 migrating pairs irrespective of the number of tables in it. When the first four rounds are complete, the boards move down one section or block, and the migrating pairs move up one section. This again occurs after the next 4 rounds. With this number of migrating pairs and a number of tables greater than 12, it can be seen that the amount of inter-room movement is less than there would be with other movements.
The next problem is movements for 3 through 8 tables which have 4 rounds and 4 migrating pairs. These are dealt with systematically below.
3 Tables
4 Tables
5 Tables
6 Tables
7 Tables
8 Tables
