(235−156, 235, 586)-Net in Base 4 — Upper bound on s

There is no (79, 235, 587)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 3355 101644 155514 519208 780303 815626 839187 904445 399273 582056 927624 795300 602330 902294 085970 471197 470457 182494 118582 120338 458274 078065 195707 849856 > 4²³⁵ [i]
