Digital (134, 236, 264)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(236−102, 236, 4001)-Net in Base 4 — Upper bound on s

There is no (134, 236, 4002)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 12274 344419 084656 727208 328001 129555 387693 870764 954788 448078 377836 201750 499940 749915 467188 631282 124102 772739 207546 095529 462556 709061 993787 556672 > 4²³⁶ [i]
