[Haskell-beginners] Creating a Triple List from a List

[A. Mc.]

Hello,

What is the best way to take:
[1, 2, 3, 4 ]

And convert it to:

[ [ [ 1 ], [ 2 ] ], [ [3]. [4] ] ]

so that each member pair is:

[ [1], [2] ]

roughly analogous to a 1x2 vector?

Thanks in advance and thank you for your time.
