(109−57, 109, 507)-Net over F₂₇ — Digital

Digital (52, 109, 507)-net over F₂₇, using

Gilbertâ€“VarÅ¡amov bound [i]

(109−57, 109, 144199)-Net in Base 27 — Upper bound on s

There is no (52, 109, 144200)-net in base 27, because

1 times m-reduction [i] would yield (52, 108, 144200)-net in base 27, but
- the generalized Rao bound for nets shows that 27^mÂ â‰¥ 38669 573249 299109 143150 467447 785557 002762 782318 458585 039305 170476 548586 187601 459874 587520 399150 448460 991075 970134 090809 091832 982289 569143 774503 735795 611969 > 27¹⁰⁸ [i]
