In one embodiment, each of the short edges of the board is in contact with a groove at one end and a tongue end at the other, and each of the long edges includes an equal number of tongues and grooves. In another embodiment, each of the long edges has a groove at each of its ends and the grooves are equal to or longer than the longitudinal length of a tongue.
