Gilbertâ€“VarÅ¡amov bound [i]

(141, 245, 4585)-Net in Base 4 — Upper bound on s

There is no (141, 245, 4586)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 3216 924864 242473 093211 253460 592282 241006 253149 585197 414951 081315 540024 109218 409105 263953 978873 108244 275786 959320 034187 917970 440934 387185 465160 264120 > 4²⁴⁵ [i]
