ALS Notation Question

Post by Sudtyro »

Code: Select all

.    .   .  |  .  .  .  |  .  .   .

With an ALS-XZ rule applied to sets A and B above, then X=6 (restricted common), and Z=3, so r2c13 <> 3. What is the proper Eureka notation for the rows and columns in set A, which is a case where the ALS cells don’t all lie in the same row or column? Do you simply use r23c12, or something else, since there might be other candidates in r2c1? And if the former, then is the proper AIC written as, say:
(3=796)r23c12 – (6=3)r2c8 => r2c13 <> 3?

For an unordered set, you can use a vertical bar to list the members, like this:

Code: Select all

&#40;3=796&#41;r2c2|r3c12 - &#40;6=3&#41;r2c8 => r2c13 <> 3

Thanks for the quick reply! Yes, the vertical bar...I've seen that before for unordered sets...probably in SudoPedia...just didn't sink in.

Sure will be nice to get over this "beginner" stage...
