Associated with any irrational number α>1 and the function g(n)=[αn+12] is an array {s(i,j)} of positive integers defined inductively as follows: s(1,1)=1, s(1,j)=g(s(1,j1)) for all j2, s(i,1)= the least positive integer not among s(h,j) for hi1 for i2, and s(i,j)=g(s(i,j1)) for j2. This work considers algebraic integers α of degree 3 for which the rows of the array s(i,j) partition the set of positive integers. Such an array is called a Stolarsky array. A typical result is the following (Corollary 2): if α is the positive root of xkxk1x1 for k3, then s(i,j) is a Stolarsky array.
