It's not clear whether the back story to this post is the escape from constraint of anyone else's opinion, or simply the claim of absolute superiority of one's own thinking. This uncertainty is a meta-puzzle in itself, and it is one that may merit its own thread. However, this forum is for questions about logic and math, so if such a thread is started it should be placed in the Others forum. Further posts of this type are subject to deletion. Regarding the current thread, the author of the OP put "red ends" in his drawing, and he confirmed, when the question was raised, they are part of the required symmetry of the solving configuration.
