(145, 243, 2172)-Net in Base 3 — Upper bound on s

There is no (145, 243, 2173)-net in base 3, because

the generalized Rao bound for nets shows that 3^mÂ â‰¥ 88 685229 383150 583474 951326 652077 947014 155946 767915 970161 775261 523904 767505 904904 791758 792641 619217 164778 966476 797755 > 3²⁴³ [i]
