(138, 138+102, 1696)-Net in Base 3 — Upper bound on s

There is no (138, 240, 1697)-net in base 3, because

the generalized Rao bound for nets shows that 3^mÂ â‰¥ 3 292773 407506 577491 946255 164012 282952 846461 112716 236756 536322 630619 334477 810152 515363 359342 985098 506351 050777 348315 > 3²⁴⁰ [i]
