(201−132, 201, 524)-Net in Base 4 — Upper bound on s

There is no (69, 201, 525)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 10 542510 107880 119167 409609 188055 642837 306415 506137 977677 370592 898713 774188 607968 661460 295447 679929 809422 364613 371567 318896 > 4²⁰¹ [i]
