Gilbertâ€“VarÅ¡amov bound [i]

(150, 150+108, 5214)-Net in Base 4 — Upper bound on s

There is no (150, 258, 5215)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 214581 011470 848447 133068 149937 060551 898151 510409 788556 410405 672475 983326 646426 648562 697769 656243 576252 194420 526099 695573 434117 936803 888463 193221 527800 795170 > 4²⁵⁸ [i]
