I wouldn't mind seeing something of an octagon, although I have no idea how to work out the logistics :P

Since you're bringing this up, we could have the following 7x7 parallelogram:

Code: Select all
      3 7 1 4 6 5 2
     1 4 6 5 2 3 7
    6 5 2 3 7 1 4
   2 3 7 1 4 6 5
  7 1 4 6 5 2 3
 4 6 5 2 3 7 1
5 2 3 7 1 4 6


Where each row & "column" & "pan-diagonal" has the digits 1 to 7.
Furthermore, each hexagon of 7 digits are all 1 to 7.

But this example is a bit too regular (the configuration of each row/column/hexagon is almost identical).
I wonder if we can have a more randomized version. Or make a 12x12 or even 19x19 parallelogram with similar properties?

An BTW, what about the star-shaped puzzle you mentioned? Could you show us the design?
