%N a(n) is the number of integer quadrilaterals (up to congruence) with integer side lengths a,b,c,d with n = Max(a,b,c,d) and integer diagonals e,f.
%C This sequence is the sum of the sequences A342720 and A342722 which deal with concave and convex quadrilaterals respectively.
%F a(n) = A342720(n) + A342722(n).
%e a(6)=1 because the only integer quadrilateral with longest edge length 6 is a trapezoid with sides a=6, b=5, c=4, d=5 and diagonals e=f=7.
%Y Cf. A342720, A342721, A342722, A342723, A344529.
