6 number combinations from 1 to 80 numbers?
Can someone send me a list of all the possible combinations of 6 numbers from 1 to 80. like 1,2,3,4,5,6 - 1,2,3,4,5,7 - 1,2,3,4,5,8 to 1,2,3,4,5,80 then 2,3,4,5,6,7 - 2,3,4,5,6,8 to 2,3,4,5,6,80 etc, Here's the deal though. 2,3,4,5,6,7 and 7,6,5,4,3,2 are the same combination and I don't want repeated combinations. the list should be under 8000 combinations that way
Wasn't looking for how many combinations there are but what are the combinations. Also remember that 1 2 3 5 6 4 and 4 3 2 1 6 5 and 3 4 2 5 6 1 are all the same combination and I don't want repeats so the list will be under 8000 combinations

Just find a pick 6 lottery that has a combination up to 80. They will eventually go through all the combinations if you are patient.

I was too lazy to calculate the number of combinations on my own, so I went to Wolfram. There are over 300 million combinations = C(80,6) That is a lot of combinations.
[Edit]
There are indeed overr 300 million combinations. The number of permutations would be even larger. The equation for the number of combinations is 80x79x78x77x76x75 / 6!. If the order mattered then you would not divide by 6! = 720.
What do you want to do with all these combinations? I could give you a program written in Python to generate them. I was thinking that you might want to choose one at random. I could also give you a program to choose one at random
