As I was born in Kióto as a Rubik's Cube, my understanding of the English language is not as thorough as that of mathematics. If you find anything in my nodes which could be expressed more elegantly or error free, please be so kind to send me a message. Any help in improving my skills will be appreciated.
Just in case anyone wonders where I put the writeups that contain more absurdness than factual information: \http://err.antville.org \
