Yikes. Another of those that need multiple apparently unrelated eliminations for the result. Though you only need one of the 2s. Love it.
Thanks, Steve! (Added: I like yours too! I just hadn't had time to look at others' solutions yet when I first replied. Embedded almost-patterns are my favorites!)
What would you say to:
(28=4)r1c94 - r3c9&r4c4 = (41)r3c56|(1)r4c4 - (1=24)r4c62 - 4r8c2 =UR= 2r78c28&(48)r78c3 => -2 r2c8,r7c9, -8 r7c4; stte ?
It took a minute to figure out that last link.
I understand, and yes, yours is definitely clearer. I have to admit that I consciously sacrificed clarity for the nice symmetry
Originally I wrote it: (4=UR=168,2)b7p253,r78c8, but then grudgingly chose to break my own rule of always including the passenger digits. In fact, I was going to add an external explanation for that link, but forgot. Thanks for reminding! I hope it's clear now.
Btw, either way you write it, it's a bit confusing that the =UR= only applies to a part of the link, but I don't see any reasonable way around it.
