Staying out of trouble, Daniel?

How about an oddagon for this one.

Code:
 *-----------------------------------------------------------*
 | 16    9     4     | 3     7     5     | 8     2     16    |
 | 5     3     16    | 8     2     9     | 167   67    4     |
 | 8     2     7     | 4     6     1     | 5     9     3     |
 |-------------------+-------------------+-------------------|
 |*46    5     2     | 7     1     3     |*46+9  8     69    |
 | 19    7     19    | 6     4     8     | 3     5     2     |
 | 3    *46    8     | 9     5     2     | 1467  467   167   |
 |-------------------+-------------------+-------------------|
 | 4679  1     3     | 5     8     467   | 2     467   679   |
 | 2    *46    5     | 1     9     467   |*46+7  3     8     |
 | 4679  8     69    | 2     3     467   | 4679  1     5     |
 *-----------------------------------------------------------*

Hello Luke451,

Yes, those oddagon patterns are so effective, yet I seldom notice them. _ Sad _

Congratulations on a great find!

Regards, Danny
