(144, 240, 2229)-Net in Base 3 — Upper bound on s

There is no (144, 240, 2230)-net in base 3, because

the generalized Rao bound for nets shows that 3^mÂ â‰¥ 3 234385 045460 049409 240935 976721 353933 417746 840364 717650 632477 115308 990707 729712 168610 320084 026529 266396 026432 312801 > 3²⁴⁰ [i]
