(84, 84+140, 700)-Net in Base 4 — Upper bound on s

There is no (84, 224, 701)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 733 354778 466645 772963 541116 520776 768354 777513 817633 218042 518372 988616 065745 978275 202089 880108 498090 961141 469763 950719 824351 793328 405960 > 4²²⁴ [i]
