Inverse of a particular matrix

[LaurV]

Why? What's wrong with Matjax? The forum uses Matjax.

\[(H^{-1})_{ij} = (-1)^{i+j}(i + j - 1) \binom {n + i - 1}{n - j} \binom {n + j - 1}{n - i} \binom {i + j - 2}{i - 1}^2\]
or inline text: \((H^{-1})_{ij} = (-1)^{i+j}(i + j - 1) \binom {n + i - 1}{n - j} \binom {n + j - 1}{n - i} \binom {i + j - 2}{i - 1}^2\) (just replaced dollars with \( etc. in Serge's formula)

Yes, I know.

Mathjax is JS, so therefore not happening here.

mimeTeX is an entirely separate little program that doesn't use TeX or its fonts in any way.

That's the reason why it looks so bad.

Looks fine to me. Better than the run-on line of text.

This is what I see (with backslash replaced by forward slash to prevent your fancy JS from seeing it):
/((H^{-1})_{ij} = (-1)^{i+j}(i + j - 1) /binom {n + i - 1}{n - j} /binom {n + j - 1}{n - i} /binom {i + j - 2}{i - 1}^2/)
