How many tickets can I get selecting 6 numbers from 1 to 40 for each play?

Question

Can anybody tell me tht how many tickets (1 ticket should contain 6 different numbers from 1 to 40) will be total, if u pick 6 numbers from 1 to 40 that non of numbers should be missing and numbers shouldn't be identical ? Each number should be unique..For example. if we need to pick 2 numbers from 1 to 4 to win, we can make total 6 tickets based on sleceting 2 numbers from 1 to 4 like this: 1,2------1,3------1,4----------2,3-----2... so how many sets will be made by picking 6 unique numbers from 1 to 40 as we picked 2 unique numbers from 1 to 4 for each play?? I must say tht person will be most intelligent who gives me answer of this question..
