(106−49, 106, 1068)-Net over F₂₇ — Digital

Digital (57, 106, 1068)-net over F₂₇, using

Gilbertâ€“VarÅ¡amov bound [i]

(106−49, 106, 689601)-Net in Base 27 — Upper bound on s

There is no (57, 106, 689602)-net in base 27, because

1 times m-reduction [i] would yield (57, 105, 689602)-net in base 27, but
- the generalized Rao bound for nets shows that 27^mÂ â‰¥ 1 964295 155485 373017 159304 904808 173478 192526 809250 527728 980990 049103 695487 983469 263258 616514 885353 429115 312817 865565 961550 313549 358610 033370 983424 717553 > 27¹⁰⁵ [i]
