(201−134, 201, 496)-Net in Base 4 — Upper bound on s

There is no (67, 201, 497)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 10 620031 867463 183341 348305 808262 199740 248437 633276 210218 789491 348387 568193 549678 524892 637991 228157 695959 669295 627594 775760 > 4²⁰¹ [i]
