(149, 149+52, 158672)-Net in Base 4 — Upper bound on s

There is no (149, 201, 158673)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 10 330433 807493 679169 792188 136615 445283 215526 396689 417812 538229 795272 787744 170259 461437 067826 644852 227174 047279 601565 535840 > 4²⁰¹ [i]
