(114, 114+114, 1837)-Net in Base 4 — Upper bound on s

There is no (114, 228, 1838)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 188411 181437 095715 709559 265904 915516 334777 481681 638651 862015 815567 973925 703178 853759 772302 762779 785704 315755 933568 882055 604846 902841 725840 > 4²²⁸ [i]
