LateXed for readability. Hopefully someone can \center the forms of numeric factors of X.

Dec 8, 2010 at 20:11 comment added Theo Johnson-Freyd A note: It's been a long time since I've seen anyone right "sigma" for the capital sigma $\sum$ that denotes a summation. A more standard word is "sum", and if you must use a letter, call it "Sigma" (capitalized) so that it doesn't read as $\sigma$. In general, note that MO does accommodate most LaTeX instructions, and moreover most of us would rather read correct raw LaTeX than a mix (you should use \times or $\times$ rather than x or $x$, for example).
