What if we could make conclusions about (0, n) and (0, N) from (e, 1) and (-f, 1)? Triangulate the right row from something unique to (0, n)?

It would be the same as how we can find the element closest to a d value, or how we can find where a given value appears as a[t]. Finding out that the grid really does do all of the work for us would be very enli[t]ening.
