(134, 134+79, 399)-Net over F₄ — Digital

Digital (134, 213, 399)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(134, 134+79, 9585)-Net in Base 4 — Upper bound on s

There is no (134, 213, 9586)-net in base 4, because

1 times m-reduction [i] would yield (134, 212, 9586)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 43 488880 313000 584457 910622 513413 063147 945220 643898 907196 836142 596358 438000 082506 684632 674272 155115 429940 953634 067305 877714 432744 > 4²¹² [i]
