(80, 80+120, 737)-Net in Base 4 — Upper bound on s

There is no (80, 200, 738)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 2 779540 463555 766377 746943 244302 667950 401324 534187 590812 310042 414429 246008 586880 148975 828799 667950 163135 987830 493884 347568 > 4²⁰⁰ [i]
