(244−132, 244, 1371)-Net in Base 4 — Upper bound on s

There is no (112, 244, 1372)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 832 513763 760198 024995 288608 361861 542127 343853 416063 443898 872467 916202 826710 030870 424667 517202 181346 829896 505729 958748 808919 578147 659457 983196 473007 > 4²⁴⁴ [i]
