(242−112, 242, 2846)-Net in Base 4 — Upper bound on s

There is no (130, 242, 2847)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 50 290579 881215 700327 190870 649507 268738 223662 122042 402391 893548 797042 048087 945631 015873 606968 808043 986533 817337 408531 086564 439508 180429 618098 303560 > 4²⁴² [i]
