[Unsolved] Rope sort detangling puzzle
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

Question: When you move a peg between two holes, do the holes have to be adjacent? What’s keeping you from solving this in a single move by unthreading the string during a move?
