Permutation help.

[jarrod0987]

What I have is a list of lists. Something like this:

[[1][4][2][3, 6][4][1]]

what I want back is something like:

[1][4][2][3][4][1], [1][4][2][6][4][1]

or even:

['142341', '142641']

How can I accomplish this please? The only ideas I have seem very convoluted.

Thanks :D
