(201−140, 201, 424)-Net in Base 4 — Upper bound on s

There is no (61, 201, 425)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 10 664925 516490 219539 182712 736768 958339 729696 671490 500988 915386 539122 784081 336579 194215 006702 330330 012995 457089 233627 295880 > 4²⁰¹ [i]
