Abstrakt: A method of constructing 28-point, 26-point and 25-point cubature formulas with polynomial precision 11 is given for planar regions and weight functions, which are symmetric in each variable. The nodes are computed as common zeros of a set of linearly independent orthogonal polynomials. [ABSTRACT FROM AUTHOR]
