MultiSquares (Posted on 2008-08-28) Difficulty: 4 of 5
A plane surface is marked with points in a square gridded format.

How many squares,
using the points as their vertices,
can be drawn within a grid of:
1. 6 x 6 points,
2. 7 x 7 points
and
3. n x n points?

In this 3 x 3 array:
   .  .  .
   .  .  .
   .  .  .  
          there are 6.
The 5th envelopes them all and
the 6th uses the outer midpoints 
of the grid as its vertices.
