Petals Around the Rose: Fraternity Register

Thanks for sharing Petals Around The Rose with us! I first heard about it in a popular science magazine, but I didn't really feel like looking it up and trying it. Somehow, while browsing the web, I stumbled upon your website and gave it a try. After approximately 15 minutes I suddenly saw the significance of the name... I really like puzzles and this feels like a really special one, because of the terms that go with understanding it... So, thanks for sharing it with us!
