The formulas mentioned in Gauss's note are not the modular equation of order 7, but a very close one; the formula for $A$ is in fact the "Multiplier equation" .The point is that confirming that $P(B,b) = 0$ (not $P(A,b)$; the equation $P(B,b) = 0$ was not written by me in the posted question) is the modular equation of order 7 would be much easier, ...
