(254−152, 254, 936)-Net in Base 4 — Upper bound on s

There is no (102, 254, 937)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 855 145275 974803 051928 267048 840221 680577 325363 676857 503585 998144 740461 745224 967234 762578 654503 782314 207066 345029 471311 007441 316817 672674 246679 124509 654800 > 4²⁵⁴ [i]
