(61, 61+31, 283)-Net over F₄ — Digital

Digital (61, 92, 283)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(61, 61+31, 9607)-Net in Base 4 — Upper bound on s

There is no (61, 92, 9608)-net in base 4, because

1 times m-reduction [i] would yield (61, 91, 9608)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 6 136791 253075 162282 329201 219847 129823 206871 324768 944528 > 4⁹¹ [i]
