I have questions about the BuckyMatrix notebook at http://www.mathsource.com/cgi-bin/msitem?0212-072 First, I wonder how the formatting is achieved. Second, I'm wondering the purpose of the undefined symbol mz in the early expressions. For instance, if mz is undefined then bm=(B@@#1&)/@mz/@Transpose[m] is equivalent to the much simpler B/@Transpose[m] and e=B@@mz[{5,6}] is equivalent to e=B[{5,6}] Ooh! Now I see! The symbol is defined near the bottom of the notebook, AFTER it's used. Not a good idea, perhaps... it certainly confused ME!

On MathSource: http://www.mathsource.com/cgi-bin/msitem?0212-072 Or as HTML: http://users.adelphia.net/~cnelson9/ An example of Bucky Numbers (fields isomorphic to the cyclotomic fields) and the Synergetics Coordinate System used to solve a problem normally solved by the LinearSolve function. Linear Programming problems can be solved the same way. I have been told some of it is not new. Can anyone tell me the name of a book or web site about something like B numbers and the Synergetics coordinate system? Cliff Nelson
