Your input (in red) is realistic; all else should have the same content as in a real mathematica session, but with different formatting.

Khovanov Homology

The coefficients of the monomials $t^{r}q^{j}$ are shown, along with their alternating sums $\chi$ (fixed $j$, alternation over $r$). The squares with yellow highlighting are those on the "critical diagonals", where $j-2r=s+1$ or $j-2r=s-1$, where $s=$0 is the signature of 9 24. Nonzero entries off the critical diagonals (if any exist) are highlighted in red.
