(122, 183, 509)-Net over F₄ — Digital

Digital (122, 183, 509)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(122, 183, 18012)-Net in Base 4 — Upper bound on s

There is no (122, 183, 18013)-net in base 4, because

1 times m-reduction [i] would yield (122, 182, 18013)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 37 606130 969974 011876 984402 616090 591295 683558 852496 469103 182592 319518 418444 779201 909961 032214 693728 231996 191760 > 4¹⁸² [i]
