(208−130, 208, 652)-Net in Base 4 — Upper bound on s

There is no (78, 208, 653)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 171997 095825 118502 715404 341176 617569 505091 109791 094753 018070 993990 902785 971326 123463 460730 414006 650228 099638 720727 235671 267760 > 4²⁰⁸ [i]
