Gilbertâ€“VarÅ¡amov bound [i]

(144, 250, 4705)-Net in Base 4 — Upper bound on s

There is no (144, 250, 4706)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 3 302992 730836 063174 662505 825110 285310 751204 181594 764518 207712 452629 967583 539236 000494 451841 051192 671922 779438 303450 535633 320708 058422 009507 776397 970000 > 4²⁵⁰ [i]
