(238−88, 238, 3242)-Net in Base 3 — Upper bound on s

There is no (150, 238, 3243)-net in base 3, because

the generalized Rao bound for nets shows that 3^mÂ â‰¥ 359428 915773 833069 789790 881559 128680 502301 430602 321056 552314 036773 511433 975905 188371 226789 988698 409768 326143 546505 > 3²³⁸ [i]
