(113, 113+57, 468)-Net over F₄ — Digital

Digital (113, 170, 468)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(113, 113+57, 16185)-Net in Base 4 — Upper bound on s

There is no (113, 170, 16186)-net in base 4, because

1 times m-reduction [i] would yield (113, 169, 16186)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 560136 943849 071283 609104 642776 233188 462208 274142 838342 255733 655216 507384 424069 888410 850963 198506 527320 > 4¹⁶⁹ [i]
