Let (k,s)-SAT be k-SAT restricted to formulas with at most s occurrences of every variable. It is known that for every k, there is an s_k such that (k,s_k)-SAT is NP-complete and (k,s_k-1)-SAT is trivial in the sense that all its instances have positive answer. In the paper, the best previously known upper bound s_k le 13/64*2
