  - F₆ from the tower of function fields by GarcÃa and Stichtenoth over F₄ [i]

(143−70, 143, 115)-Net over F₄ — Digital

Digital (73, 143, 115)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(143−70, 143, 1308)-Net in Base 4 — Upper bound on s

There is no (73, 143, 1309)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 127 214839 393762 534221 742569 091111 454399 372700 391469 991859 740068 706817 518359 221227 457120 > 4¹⁴³ [i]
