(234−120, 234, 1673)-Net in Base 4 — Upper bound on s

There is no (114, 234, 1674)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 765 038281 507731 890153 707740 559828 485626 975136 650975 916499 999151 704714 794585 688786 174022 066819 299845 689994 930404 718745 831657 092709 928218 215520 > 4²³⁴ [i]
