The declaration int (*indexes)[26] is different than int *indexes[26]. The
latter making indexes an array of 26 pointers pointing to 26 integers.  The
first is a pointer pointing to an array of 26 integers. It is explained more
clearly like this: indexes[][26].  So it really is a form of a
multi-dimensional array.  You would access the array like this:

        var = indexes[i]  which is the same as var = &indexes[0][i]

So I don't think you can assign a value to indexes since it really isn't a
pointer.  You could do something like int *idx = &indexes and then assign a
value to idx.  Play around with that and see what happens.

I had to look around for an answer to this one.  Found it in my Plum Hall book
"Reliable Data Structures in C".
