oh

> I'm 99% the tutorial's wrong and it doesn't look like 2,2,0 chains exist in monadic links.

when I saw this my first thought was "wait, did someone claim +×1->v+(ω×1), i feel like that would have been shown to be wrong pretty quickly"

but nope it was (v+ω)×1

which is just what a (2),(2,0) does

so now I can understand why it may have taken a bit to find the 0,2,2,0 counterexample, but it's also even stranger that they thought it was its own pattern in the first place

Honestly, whenever I see someone make a claim about dyadic chains, my first response it "replace the dyads with , and see if it's still true"
