(98−33, 98, 297)-Net over F₄ — Digital

Digital (65, 98, 297)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(98−33, 98, 10112)-Net in Base 4 — Upper bound on s

There is no (65, 98, 10113)-net in base 4, because

1 times m-reduction [i] would yield (65, 97, 10113)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 25130 929224 774576 332365 402498 201531 153769 356311 324219 610120 > 4⁹⁷ [i]
