(136, 183, 1513)-Net over F₄ — Digital

Digital (136, 183, 1513)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(136, 183, 182564)-Net in Base 4 — Upper bound on s

There is no (136, 183, 182565)-net in base 4, because

1 times m-reduction [i] would yield (136, 182, 182565)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 37 576701 131485 468208 836589 580799 285396 581534 856400 379957 307410 561966 355332 843751 485653 553995 664101 321195 799136 > 4¹⁸² [i]
