(81, 201, 755)-Net in Base 4 — Upper bound on s

There is no (81, 201, 756)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 10 827694 364853 107943 689775 116896 199549 910987 402204 576669 634466 168713 710718 947803 428230 270647 122495 842762 586896 807151 345360 > 4²⁰¹ [i]
