It is a recursive funtion call.  Is this clear?

:: is a list building primitive.  If you have a list of integers (ilist) 
and you want to add an integer (newi) to the front, you would use:

newi :: ilist

So in general you add a foo to a foolist with (foo::foolist).

In your case, we are adding an array to a list of arrays.
front is the first array returned by the earlier call to firstN.
group' returns a list of arrays.
