(218−94, 218, 3759)-Net in Base 4 — Upper bound on s

There is no (124, 218, 3760)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 179428 647657 665719 599330 143632 728082 449450 855843 050933 311635 571499 769731 509211 809769 249312 863872 364676 596260 027167 386498 920908 479411 > 4²¹⁸ [i]
