I had a look at the group theory page. This is definitely something that should be taught more in basic math so I was glad to see it there. But I must admit i was disappointed at the notation: yes it's colourful, but totally useless for doing calculations. And why use the plus sign for combining transformations? That seems a bit shortsighted.. John Conway's books are still much better than this somewhat chaotic webpage. It's super hard to present mathematical ideas, cool widgets are not enough.
