Yes.
If you want a more detailed answer, it might be a good idea to give an
appropriately detailed question…
Best Regards

if you have ruby version 1.8.7 or 1.9, just try it
eg,
RUBY_VERSION
=> “1.8.7”
[1,2,3].permutation(3){|x| p x}
[1, 2, 3]
[1, 3, 2]
[2, 1, 3]
[2, 3, 1]
[3, 1, 2]
[3, 2, 1]
=> [1, 2, 3]
[1,2,3].permutation(2){|x| p x}
[1, 2]
[1, 3]
[2, 1]
[2, 3]
[3, 1]
[3, 2]
=> [1, 2, 3]
[1,2,3].combination(3){|x| p x}
[1, 2, 3]
=> [1, 2, 3]
[1,2,3].combination(2){|x| p x}
[1, 2]
[1, 3]
[2, 3]
=> [1, 2, 3]
