It's called single ALS logic. The ALS is (567)ad5. Note the 5 conjugate at bd3 and 7 group conjugate at b3 and b457. (5)d3=(67)ad5 or (5)b3=(7)b456)=(6)a5 => b5,b6<>6. 06/Sep/10 4:35 AM Also there is a 67 grouped S-Wing with pivot at a5.(6)a5=bc6=(6)d6 or (7)a5=ab4=(7)ef4 => d6<>7This S-Wing is also an almost 456 continuous loop. If e4<>7 it is a continuous loop but I haven't figured out how to use this yet. 06/Sep/10 5:22 AM Wendy, are you sure that's the correct title for the photo? 06/Sep/10 5:39 AM IanI wondered too! Looks much more like northern hemisphere region than northern WA!! Misty even! 06/Sep/10 11:15 AM 1. Unique possibilities to 27.The steps are long, but I couldn't prune them down:2. If i5=7,a5=6=d6,f4=4,d5=5=f1,f5=1=e2,d8=8,d9=7;the bottom middle box is devoid of 7.So i6=7.UP28.3. If c1=2=a4,b3=5,a7=8,a5=6=d6,f4=4,d7=8,f2=1,(e4=18),b4=7,e4=8,e6=1,c7=5 (to avoid the unresolvable 368 More... 06/Sep/10 1:45 PM In step 4, there is no need for f5=1, but add b2=6 after c2=8. 06/Sep/10 5:16 PM Following farpointer's reference yesterday, to the magical poem by Lord ALFRED Tennyson, which talks about the Kraken monster in his secret cell, I promise from now on to never mention the elephant in the room again. 06/Sep/10 5:49 PM Sotir, That's an incredible amount of work to produce that list - and it's extremely useful. Very many thanks. Best regards, Neil 06/Sep/10 7:23 PM 11:28 06/Sep/10 8:42 PM Anne, You did this puzzle in less than 12 minutes? From now, I shall call you Wonder Woman.Best regards, Neil 06/Sep/10 8:45 PM
