(212−60, 212, 72123)-Net in Base 4 — Upper bound on s

There is no (152, 212, 72124)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 43 330747 331840 683396 271625 307592 421715 772926 389632 303913 688851 007158 352133 016119 689576 638914 929283 270285 170958 359611 767464 365016 > 4²¹² [i]
