Sorry I am busy at the moment Could you devise some blurb yourself Thanks Artistic billiards Thanks for nominating the article and all the hard work with DYK One request I would have liked to have know the article had been nominated prior to receiving notiification that it was already appearing in DYK If you had done so the article would have been put through a rigorous second draft to make sure it was correct in every way and I could have had some input in the wording of the extracted fact Thanks again
