(49, 49+39, 1212)-Net over F₂₇ — Digital

Digital (49, 88, 1212)-net over F₂₇, using

Gilbertâ€“VarÅ¡amov bound [i]

(49, 49+39, 1092389)-Net in Base 27 — Upper bound on s

There is no (49, 88, 1092390)-net in base 27, because

1 times m-reduction [i] would yield (49, 87, 1092390)-net in base 27, but
- the generalized Rao bound for nets shows that 27^mÂ â‰¥ 33779 179343 867559 544257 442954 661055 532524 553671 309489 117270 912998 748776 706283 786446 553406 211083 207910 891229 926721 378326 147793 > 27⁸⁷ [i]
