Recall that if the variables x, of a polynomial ring /:[.vj, JC2» •. . ,xr aie assigned nonnegative weights wit then the weighted degree of a monomial A"1 • • • A"' is 5^, a, • Wi (see [3]). Therefore, if we take the weight of the variable A* to be the magic sum of the corresponding Hilbert basis element hiy then dim*(/?c (•*)) is exactly the number of Franklin squares of magic sum s. Since Rc is a graded ^-algebra, it can be decomposed into a direct sum of its graded components Rc — © Rc(s) (see [1] or [3])
