The number of selected orders will always be equal to some multiple of the number of conditions in the experiment. This is because each condition must appear in each position of the Latin Square/table at least once, and the number of positions is equal to the number of conditions squared. Therefore, the number of selected orders will be a multiple of the number of conditions, with the exact number depending on the specific Latin Square or rotation used.
