Neuer (?) Fund über Sudoku-Geometrie

[DaleERKloss]

Phistomefel- After reading your post I have found 4 more relationships like yours but I used red rectangles instead of red squares

Would it be worthwhile posting them here???

Also what format do I need to use for the pictures of my Sudoku puzzles?

If this not appropriate for this forum or thread let me know. this my first post on this forum.
Thanks, Dale E. Kloss
