A tennis coach is trying to put together a team of four players for the forthcoming tournament. For this 7 players are available: males A, B, and C; and females W, X, Y and Z. All players have equal capability and at least 2 males will be there in the team. For a team of four, all players must be able to play with each other. But, B cannot play with W, C cannot play with Z and W cannot play with Y.

If all the three males are selected, then how many combinations of four-member teams are possible?
