(238−132, 238, 604)-Net in Base 3 — Upper bound on s

There is no (106, 238, 605)-net in base 3, because

the generalized Rao bound for nets shows that 3^mÂ â‰¥ 367827 146688 376934 760333 879992 897974 127035 946605 895358 814006 175185 647377 357082 302909 498128 336322 705070 212635 580097 > 3²³⁸ [i]
