13. A proven error in the trick score may be corrected prior to the conclusion of the game in which it occurred. Such game shall not be considered concluded until a declaration has been made in the following game, or if it be the final game of the rubber, until the score has been made up and agreed upon.
CUTTING
14. In cutting, the ace is the lowest card; as between cards of otherwise equal value, the lowest is the heart, next the diamond, next the club, and highest the spade.
15. Every player must cut from the same pack.
16. Should a player expose more than one card, the highest is his cut.
FORMING TABLES
17. The prior right of playing is with those first in the room. If there are more than four candidates of equal standing, the privilege of playing is decided by cutting. The four who cut the lowest cards play first.
18. After the table is formed the players cut to decide upon partners, the two lower playing against the two higher. The lowest is the dealer who has choice of cards and seats, and who, having made his selection, must abide by it.
19. Six players constitute a complete table.
20. The right to succeed any player who may retire is acquired by announcing the desire to do so, and such announcement shall constitute a prior right to the first vacancy.
