(242−144, 242, 914)-Net in Base 4 — Upper bound on s

There is no (98, 242, 915)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 51 860129 843339 157585 936029 696656 811658 375932 457239 761173 739482 732535 434352 138370 161019 074704 784204 945751 005778 291668 274705 807450 928881 117569 539340 > 4²⁴² [i]
