(218−60, 218, 95175)-Net in Base 4 — Upper bound on s

There is no (158, 218, 95176)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 177481 918679 870036 038489 550276 972387 591780 222704 294443 815923 599492 084675 389506 001463 888803 614478 337346 720621 483693 732403 478980 671480 > 4²¹⁸ [i]
