Popis:	Applying the methods of integral representations of combinatorial sums, G. P. Egorychev and E. V. Zima (Comm. Algebra 36, 1426–1436 (2008)) have found simple formulas for the number of classes of projectively congruent quadrics and posed the problem of finding an algebraic proof and an interpretation of the obtained formulas. The aimof the present paper is to give a solution to this problem.
