poker hands ranking order

In one version of poker 7 cards are dealt to the player (in order does not matter)?
How many different poker hands have three different pairs (Two cards of same rank) and a card from another room? Thanks
There are C (13,3) = 286 ways to choose the ranks of the pairs is C (4,2) = 6 ways to choose combinations of each pair, there are 40 letters on the left of the map odd 286 * 6 * 40 ^ 3 = 2471040
