(159, 159+62, 81073)-Net in Base 4 — Upper bound on s

There is no (159, 221, 81074)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 11 357230 283442 634114 754190 668093 650866 253167 293773 800780 711835 589030 881116 985551 692235 686056 286864 804396 046822 711864 648705 157182 364240 > 4²²¹ [i]
