@19.50, the edges should be C2-->V33 and V34 -->C2. @21.20 the cycle should pass through V11 --> C1 and C1--> V12 so that C1 is included in the ham. cycle.

It would have been nice to see the graph being represented as well

This solution is wrong. I've seen it used elsewhere and when challenged they admit they are not sure. You need to connect clauses to dedicated nodes with gap nodes in each vertex row. So if you have k clauses, you need 3k+3 nodes in each row. Correct proofs all use this as it enforces the row traversal to be contiguous. Otherwise you can go into clauses c1 or c2 and come out somewhere else and it does happen. A counterexample is straightforward. It's not impressive people keep copying invalid proofs. 2k nodes=bad proof that was copied from other bad proofs. Go find the 3k+3 ones, it's an obvious blunder. Code it even!!
