(29, 29+71, 133)-Net in Base 4 — Upper bound on s

There is no (29, 100, 134)-net in base 4, because

extracting embedded orthogonal array [i] would yield OA(4¹⁰⁰, 134, S₄, 71), but
- the linear programming bound shows that MÂ â‰¥ 4 182572 330796 791383 567951 825792 735180 658653 040900 409295 768511 365287 782622 776199 465756 786688 / 2 490480 234655 460492 562148 078125 > 4¹⁰⁰ [i]
