(240−112, 240, 2706)-Net in Base 4 — Upper bound on s

There is no (128, 240, 2707)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 3 125716 879119 265196 147523 252891 265662 348902 532731 983914 492457 325205 381549 785611 684698 946742 544532 402073 104641 728334 439205 771195 550935 108926 760560 > 4²⁴⁰ [i]
