(82, 82+158, 616)-Net in Base 4 — Upper bound on s

There is no (82, 240, 617)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 3 249689 448053 871474 786853 477530 380500 103172 949618 496500 526151 584838 910158 760980 760078 307214 444737 774233 927547 226268 477807 390986 281917 337755 660384 > 4²⁴⁰ [i]
