(241−130, 241, 1372)-Net in Base 4 — Upper bound on s

There is no (111, 241, 1373)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 12 958185 927021 071270 866230 194221 485885 774630 543671 003005 867551 334033 683335 981763 223857 753158 086105 923008 214691 074189 417119 299729 435427 851349 908696 > 4²⁴¹ [i]
