(117, 117+116, 1914)-Net in Base 4 — Upper bound on s

There is no (117, 233, 1915)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 192 067077 454501 267519 295080 504391 190535 071659 487685 275386 244809 207438 374235 768082 420390 853124 149019 110029 808359 938643 299591 667104 164092 138595 > 4²³³ [i]
