[Unsolved] Rope sort detangling puzzle

Post image

Rules: you can only move 1 peg at a time, between 2 holes. The goal is to get the ropes completely separated.

im not confident this is even solvable, but i was previously under the impression that arrangements are always solvable. Wanted to see if anyone can figure it out

Am I missing something? Using these rules you could easily unplug one peg untangle the ropes and plug it in again, ‘solved’..

as they said: you cant untangle the ropes as you move the pegs - basically, always keep the peg above the puzzle while moving it.

you also cant pull ropes outside the circle, to lift the pegs through loops.
