(136, 256, 2815)-Net in Base 4 — Upper bound on s

There is no (136, 256, 2816)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 13682 957058 417219 549438 321003 864091 690421 146858 200011 900446 863519 518011 553666 958301 425989 064794 802699 473532 776427 800930 479186 756326 784351 580292 549847 834345 > 4²⁵⁶ [i]
