(128, 260, 1940)-Net in Base 4 — Upper bound on s

There is no (128, 260, 1941)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 3 543971 657405 029934 492377 676690 528766 431571 462537 028558 491226 881493 078051 533170 558871 102250 188666 677325 274388 980047 761992 092839 713605 201934 083372 091404 488764 > 4²⁶⁰ [i]
