(112, 112+61, 397)-Net over F₄ — Digital

Digital (112, 173, 397)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(112, 112+61, 11338)-Net in Base 4 — Upper bound on s

There is no (112, 173, 11339)-net in base 4, because

1 times m-reduction [i] would yield (112, 172, 11339)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 35 918467 226454 393364 030621 596341 527538 544404 023254 414211 467374 261824 708041 350944 804397 334156 807505 816720 > 4¹⁷² [i]
