(225−112, 225, 1853)-Net in Base 4 — Upper bound on s

There is no (113, 225, 1854)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 2977 389487 827962 216177 822000 472071 173365 179008 465804 299137 287151 794532 164224 602310 923210 794567 483389 297834 918949 259261 242021 292727 895267 > 4²²⁵ [i]
