(70, 70+136, 527)-Net in Base 4 — Upper bound on s

There is no (70, 206, 528)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 11872 712171 838437 414221 540250 953892 022846 299737 833891 831564 926333 326968 833177 170661 172288 331182 493477 445551 937819 301493 749400 > 4²⁰⁶ [i]
