Sums of Four Squares,eneralization. There are two types of questions to be considered: . — how can one compute representations of a number as a sum of two or four (or possibly some other number) of squares? — and . — is there a structure on the set of representations that allows their number to be determined in an elementary manner?

Sum Set Cardinalities of Line Restricted Planar Sets,ge |X|, then c=1 suffices for 2 ≤ X < 3, and any value of c < (4-λ)/2 suffices for 3 ≤ λ < 4. At the same time, if (4-λ)/2=l/. for .∈ {1,2,…}, then no value of c > 1/k can give the desired result, even when |X| is restricted to be large.
