(243−152, 243, 755)-Net in Base 4 — Upper bound on s

There is no (91, 243, 756)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 207 557754 479869 896256 220913 923519 224227 669584 402077 711452 106285 807350 951425 182065 886448 072376 868855 859331 803692 057551 657969 250910 736241 815363 497116 > 4²⁴³ [i]
