Formation of Table.
17. If there are more than four candidates, the players are selected by cutting, those first in the room having the preference. The four who cut the lowest cards play first, and again cut to decide on partners; the two lowest play against the two highest; the lowest is the dealer, who has choice of cards and seats, and, having once made his selection, must abide by it.
18. When there are more than six candidates, those who cut the two next lowest cards belong to the table, which is complete with six players; on the retirement of one of those six players, the candidate who cut the next lowest card has a prior right to any after-comer to enter the table.
