(78, 220, 610)-Net in Base 4 — Upper bound on s

There is no (78, 220, 611)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 3 127444 500604 088539 238478 027169 781988 570377 637590 626656 490006 573342 154938 404330 347581 718807 901333 170436 861638 801289 738203 246349 068224 > 4²²⁰ [i]
