This hanjie is a demonstration about symmetry and logic. It is not a pretty picture. Apologies. I was challenged to create a specific hanjie by Baggy T. It is as close an approximation to what was asked as is possible.
It is tested and is 100% logical without requiring the use of temps.
However... my previous point still stands. Good attempt, but as a mathematician, "close" just doesn't quite cut it. In a week or so, when I have a bit more time to get back into creating puzzles, I'll give this challenge a go myself. But I'm not hopeful.
For those wondering, I posted the challenge here:
