(103−51, 103, 679)-Net over F₂₇ — Digital

Digital (52, 103, 679)-net over F₂₇, using

Gilbertâ€“VarÅ¡amov bound [i]

(103−51, 103, 270767)-Net in Base 27 — Upper bound on s

There is no (52, 103, 270768)-net in base 27, because

1 times m-reduction [i] would yield (52, 102, 270768)-net in base 27, but
- the generalized Rao bound for nets shows that 27^mÂ â‰¥ 99 802441 746093 121864 195966 488821 318755 859765 943580 920333 071123 632503 602655 714111 493884 489712 631891 825951 698531 729728 825168 206599 529434 155564 690657 > 27¹⁰² [i]
