(120, 260, 1487)-Net in Base 4 — Upper bound on s

There is no (120, 260, 1488)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 3 511780 608205 833739 846102 073658 421236 513942 970248 359408 708991 289474 780819 866200 180867 963240 441449 239095 975721 684832 218027 998944 401728 935915 258127 519657 557591 > 4²⁶⁰ [i]
