  In a recent paper (Phys. Rev. A 90, 022316 (2014) ), Goyeneche et al.
established a link between the combinatorial notion of orthogonal arrays and
k-uniform states and present open issue. (B) Find for what N there are
3-uniform states of N-qubits. In this paper, we demonstrate the existence of
3-uniform states of N-qubits for N=11,..,15".
