(108, 250, 1140)-Net in Base 4 — Upper bound on s

There is no (108, 250, 1141)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 3 402293 236048 582801 767198 923321 401930 166775 019253 295336 498001 292860 789828 049171 514653 754141 764806 860300 993926 519834 930271 642671 013986 493414 240883 691536 > 4²⁵⁰ [i]
