(140, 140+108, 1575)-Net in Base 3 — Upper bound on s

There is no (140, 248, 1576)-net in base 3, because

the generalized Rao bound for nets shows that 3^mÂ â‰¥ 21521 575042 735027 140973 595538 998751 763322 057849 936806 788172 431586 945607 236078 652689 190387 546076 039769 262465 713045 673457 > 3²⁴⁸ [i]
