We investigate the relation between the number of representations of an integer $n$ by sums of the form $a_1+ \dots+a_k$, where $a_1, \dots, a_k \in A$,and the size of $A$. Some related problems are also considered. %K Additive basis %K sumset %K square of a polynomial. %U http://www.boku.ac.at/MATH/udt/vol03/no2/Dub08-2.pdf
