(223−132, 223, 863)-Net in Base 4 — Upper bound on s

There is no (91, 223, 864)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 190 507583 124035 566807 793403 511179 574387 038120 960144 576073 842029 007337 713844 530284 058957 768566 820484 338985 275188 282604 994083 741498 851305 > 4²²³ [i]
