Permutations (general terms )

It is possible to 'perm' bets or selections. For example, if you made 3 selections, (x, y and z) you could perm all the possible doubles. In this case 3 individual bets would be possible; xy, xz, and yz, a total of 3 bets or lines. Similarly, with 4 selections, (w, x, y and z) the possible doubles could again be permed and would become wx, wy, wz, xy, xz and yz; now 6 individual bets or lines.
