Hi All,

I have a bit of bother here about creating a list.  The problem: Given a
set of lists of the same dimension, example
list={{1,2},{2,3},{5,6},{7,8}}, I want to join them in sets of two such
that every combination is joined.  So, if list is of Dimensions={5,2},
the new list will be of Dimensions={10,2,2}.  I think that states the
basic problem.  I want to use standard issue Mathematica functions
without calling up a package, or simulating the style of another
program language like Pascal.

Thanks in advance for any help.

Dan
