(226−61, 226, 1460)-Net over F₄ — Digital

Digital (165, 226, 1460)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(226−61, 226, 131533)-Net in Base 4 — Upper bound on s

There is no (165, 226, 131534)-net in base 4, because

1 times m-reduction [i] would yield (165, 225, 131534)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 2907 667795 185245 679968 329885 491602 736988 500067 280508 236596 602453 892942 574775 795610 887523 731276 053392 760362 391756 621670 810548 964527 920384 > 4²²⁵ [i]
