Digital (142, 208, 385)-net over F₃, using

Gilbertâ€“VarÅ¡amov bound [i]

(142, 142+66, 6660)-Net in Base 3 — Upper bound on s

There is no (142, 208, 6661)-net in base 3, because

the generalized Rao bound for nets shows that 3^mÂ â‰¥ 1744 701830 999457 240552 926025 671140 430748 234273 400950 490628 492546 849249 946011 254672 763432 855038 205835 > 3²⁰⁸ [i]
