[edit] 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 = -3 is the signature of L11a208. Nonzero entries off the critical diagonals (if any exist) are highlighted in red.    Data:L11a208/KhovanovTable
