Gilbertâ€“VarÅ¡amov bound [i]

(154, 154+92, 9912)-Net in Base 4 — Upper bound on s

There is no (154, 246, 9913)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 12836 081604 369117 454300 387357 117113 787152 623388 118749 929859 273153 935275 501101 931236 055855 928044 053876 532802 937308 621822 975533 072482 189664 400777 892280 > 4²⁴⁶ [i]
