(240−144, 240, 470)-Net in Base 3 — Upper bound on s

There is no (96, 240, 471)-net in base 3, because

the generalized Rao bound for nets shows that 3^mÂ â‰¥ 3 554403 332270 128409 690065 044085 806049 062450 624649 831956 027420 231130 652441 289906 753424 660099 691335 169918 756208 703473 > 3²⁴⁰ [i]
