(104, 104+150, 987)-Net in Base 4 — Upper bound on s

There is no (104, 254, 988)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 864 114082 560506 467078 641623 295769 797650 464979 392680 647276 174125 012986 523152 819796 569588 491029 189243 526108 635795 227301 628258 770015 625826 687463 718010 974191 > 4²⁵⁴ [i]
