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=<*s*> is the signature of
T(<*m*>,<*n*>). Nonzero entries off the critical diagonals (if
any exist) are highlighted in red.
