(193−116, 193, 707)-Net in Base 4 — Upper bound on s

There is no (77, 193, 708)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 163 371442 077376 693477 135907 907330 131964 829236 434043 919581 707790 878056 371603 930377 491090 885699 712996 146385 404887 004600 > 4¹⁹³ [i]
