AICs with 9 links - and new original names

Postby 999_Springs » Wed Jul 24, 2013 9:00 pm

This thread is a continuation of that other thread I did where I documented all the patterns of nice loops with 6, 7, and 8 links along with suggested names. (The only possible pattern with 5 links is a turbot fish.)

I got bored so I compiled all the possible patterns for 9 links. That's 4 strong and 5 weak links, so you'll always get a discontinuous loop. These forcing chains will always be characterised by a rating of 7.2 on SE (except the last one which is an X-Chain and is 6.8).

I'm pretty sure I've got them all. I've found 30 of them. Here they are, sorted by the number of cells used in the pattern (including the elimination). Most of the names are mine.

Tell me if I'm missing a pattern or an elimination or got a duplicate or anything.

20. The last thing the pencilmark remembered was his alarm clock displaying 8:36 before two bivalue cells surrounded him. One of them shackled him to the bed with a heavy iron chain, nine links long. The other bivalue grinded his filthy claws across his chest, his other hand muffling his screams. #1r3c7 woke up, relieved it was all a dream. But as he saw his clock read 8:35, a shadowy figure filled the doorway, and the hinges creaked. Meanwhile, some random guy in cyberspace clicked "Take step".
