(131, 131+124, 2337)-Net in Base 4 — Upper bound on s

There is no (131, 255, 2338)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 3390 269655 227956 943059 446439 201301 753647 989211 088340 910629 421971 265524 798770 111354 564736 349345 944647 842176 230279 665812 226436 932509 237480 337059 072556 032640 > 4²⁵⁵ [i]
