(118, 118+118, 1899)-Net in Base 4 — Upper bound on s

There is no (118, 236, 1900)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 12491 535492 156811 190635 488933 302892 622480 078228 676364 745216 268452 427681 546925 145847 232145 114331 462518 842783 251288 590830 457678 783169 175353 117356 > 4²³⁶ [i]
