(109, 109+132, 1284)-Net in Base 4 — Upper bound on s

There is no (109, 241, 1285)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 13 019442 550620 318135 288537 102475 902680 052179 594133 088551 029873 168251 540522 507985 425538 646465 384883 110293 865125 962359 626382 941719 318587 038750 317000 > 4²⁴¹ [i]
