I know that there is combination function whthin package 'Combinatorics’

which gives me all possible combination without regarding order of elements

```
x = combinations([1,2,3], 3)
# which gives this
collect(x) => [1,2,3]
# but I couldn't find function for getting this.
=> [[1,2,3], [2,1,3], [3,1,2], [3,2,1]]
```

I looked up “Combinatorics” and “Iterators” Packages, but couldn’t find function I need.

thanks for your time.
