(124, 124+132, 1779)-Net in Base 4 — Upper bound on s

There is no (124, 256, 1780)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 13701 907319 066185 777715 999321 277417 387929 470381 123033 500097 592338 537704 191286 285201 298303 680641 216011 872092 452660 989824 667492 213316 632105 185485 149723 443815 > 4²⁵⁶ [i]
