That's very cool! I wanted to use a loop as well, but couldn't do it in one (simple) step. Glad you did!
(& other eliminations from the loops)
You say loops. Just to make sure I didn't miss something, do you see more than one loop in that chain or is that a typo? I only see the embedded 9r1c2==9r3c2-loop (a Grouped M-Ring, btw) with the extra unlisted eliminations -9r12c3, -2r1c3789. As written, the outer chain is not a loop (and you correctly didn't mark it as such either) as it has overlapping end points. It could be written as one (9r1c2==9r1c6-loop), but it's more complicated and doesn't provide any benefits. I prefer the way you wrote it!
