(7, 7+48, 12685)-Net in Base 256 — Upper bound on s

There is no (7, 55, 12686)-net in base 256, because

the generalized Rao bound for nets shows that 256^mÂ â‰¥ 2 841656 739751 727806 015466 361262 937936 795739 914796 875456 620522 699929 666441 089330 869555 938032 173856 415758 014431 105211 362339 776639 641096 > 256⁵⁵ [i]
