(143, 143+90, 2559)-Net in Base 3 — Upper bound on s

There is no (143, 233, 2560)-net in base 3, because

the generalized Rao bound for nets shows that 3^mÂ â‰¥ 1492 020600 319870 440599 132623 727764 350456 552497 616832 221100 401271 445853 639005 460736 535384 950160 852668 234883 396609 > 3²³³ [i]
