The coefficients of the monomials are shown, along with their alternating sums (fixed , alternation over ). The squares with yellow highlighting are those on the "critical diagonals", where or , where 4 is the signature of 10 5. Nonzero entries off the critical diagonals (if any exist) are highlighted in red.
