(157, 239, 4836)-Net in Base 3 — Upper bound on s

There is no (157, 239, 4837)-net in base 3, because

the generalized Rao bound for nets shows that 3^mÂ â‰¥ 1 079888 730481 167386 406005 056338 753546 534703 728404 804111 709030 758377 485951 766686 066568 284251 340179 829555 424426 151595 > 3²³⁹ [i]
