Thanks Immp.
Code:
+--------------+--------------+--------------+
| 358 6   35   | 1   57  578  | 2   4   9    |
| 9   12  7    | 34  34  26e  | 16  5   8    |
| 158 4   25   | 26a 9   58   | 3   7   16   |
+--------------+--------------+--------------+
| 6   78  4    | 5   2  79c   | 89  1   3    |
| 17  127 9    | 8   67  3    | 4   26  5    |
| 35  238 235  | 69b 1   4    | 89  26  7    |
+--------------+--------------+--------------+
| 347 37  6    | 47  8   25   | 15  9   12   |
| 2   5   1    | 369 36  69d  | 7   8   4    |
| 47  9   8    | 247 45  1    | 56  3   26   |
+--------------+--------------+--------------+


Start at a and go to e. If you plug a 6 into r3c4 (a) and follow the letters that then puts a contradictory 6 into (e) at r2c6 which evicts the 6 at the start point (a).

So r3c4 (a) < > 6.


Eureka

6r3c4-(6=9)r6c4-r4c6=(9-6)r8c6=6r2c6-(6)r3c4

I, too, have about the same opinion as you. It doesn't have to be otherwise. Although opinions may differ after all. I recently did a paper on this, I found http://essaypapers.reviews/for it. Anything can happen in life and we can't influence some things. We can only adapt to them. This is my personal point of view.


thanks
