(249−152, 249, 461)-Net in Base 3 — Upper bound on s

There is no (97, 249, 462)-net in base 3, because

the generalized Rao bound for nets shows that 3^mÂ â‰¥ 71916 936290 403529 305646 012935 856355 527510 375561 516775 565248 858139 112638 541762 570536 284192 731627 199953 574427 649309 064025 > 3²⁴⁹ [i]
