(238−104, 238, 3797)-Net in Base 4 — Upper bound on s

There is no (134, 238, 3798)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 196206 169102 152459 765103 865685 513333 784284 933716 384340 052668 701895 505993 840562 748016 332351 073145 100705 898060 514047 940095 603605 992602 094846 859310 > 4²³⁸ [i]
