(226−112, 226, 1900)-Net in Base 4 — Upper bound on s

There is no (114, 226, 1901)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 11703 959284 293605 513268 753247 610706 111391 083875 615912 475366 170759 598214 277294 048386 546199 369705 397749 934636 931721 149287 183399 302722 044220 > 4²²⁶ [i]
