(259−120, 259, 3020)-Net in Base 4 — Upper bound on s

There is no (139, 259, 3021)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 865127 105211 430196 162910 852510 840781 261607 600896 133003 227767 027433 972068 070569 962430 264400 582955 785109 702303 051914 468774 240232 751611 013956 835770 938817 699116 > 4²⁵⁹ [i]
