(248−128, 248, 809)-Net in Base 3 — Upper bound on s

There is no (120, 248, 810)-net in base 3, because

the generalized Rao bound for nets shows that 3^mÂ â‰¥ 22094 414896 300099 336593 138673 415003 903042 067670 941015 692489 172559 382957 196509 615777 244075 214718 072485 659130 378121 133697 > 3²⁴⁸ [i]
