(87, 87+130, 801)-Net in Base 4 — Upper bound on s

There is no (87, 217, 802)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 45207 465011 885704 350165 130793 709755 831803 158835 765498 535101 216910 390831 013491 400431 615099 694514 354503 833361 374981 945834 561246 768452 > 4²¹⁷ [i]
