(207−108, 207, 1376)-Net in Base 4 — Upper bound on s

There is no (99, 207, 1377)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 43743 164898 176896 736668 856176 062083 374397 571051 266705 249150 493824 013973 776211 254611 959356 398718 542164 913293 131414 952885 346464 > 4²⁰⁷ [i]
