If there are 11 combinations of brackets my script is wrong since I only had 7. It is easy to fix but it would add another 100 characters to my script.

Initially, I thought the extras were just simple rotations of the orginal 7 but I could be wrong. The java script on the web only deals with 7 basic permutations as well. I am too tired right now to worry it out though.

As to your question, all contributions are welcome but this is just a fun thing & I don't think we need to over do it.
