(240−124, 240, 1657)-Net in Base 4 — Upper bound on s

There is no (116, 240, 1658)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 3 214954 191856 512207 415605 275768 443263 759126 805344 205930 137880 130684 838560 647062 713220 209633 393342 915874 123113 185517 752656 671410 723777 461954 185440 > 4²⁴⁰ [i]
