### Khovanov Homology

 The coefficients of the monomials trqj are shown, along with their alternating sums χ (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 L11n408. Nonzero entries off the critical diagonals (if any exist) are highlighted in red. Data:L11n408/KhovanovTable
