693 thread should be sorted before the other. If you use more than one
694 function, the primary sort function should be the last. You should
695 probably always include `gnus-thread-sort-by-number' in the list of
696 sorting functions -- preferably first. Also note that sorting by date
697 is often much slower than sorting by number, and the sorting order is
698 very similar. (Sorting by date means sorting by the time the message
699 was sent, sorting by number means sorting by arrival time.)

702 `gnus-thread-sort-by-author', `gnus-thread-sort-by-subject',
