Digital (127, 205, 353)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(205−78, 205, 7466)-Net in Base 4 — Upper bound on s

There is no (127, 205, 7467)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 2649 455621 625650 650826 473284 367983 507449 222964 749766 243334 890382 072563 080751 092475 396038 579932 820093 257092 721641 894611 205280 > 4²⁰⁵ [i]
