(138, 138+108, 1510)-Net in Base 3 — Upper bound on s

There is no (138, 246, 1511)-net in base 3, because

the generalized Rao bound for nets shows that 3^mÂ â‰¥ 2384 228544 473412 590937 103001 420076 368820 815393 522616 148053 640932 873453 676309 671632 636289 347593 072508 626200 366086 454309 > 3²⁴⁶ [i]
