(142, 142+64, 32001)-Net in Base 4 — Upper bound on s

There is no (142, 206, 32002)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 10585 987946 311066 494572 765276 973215 577165 515046 910685 153228 867761 251683 233193 540993 385280 830838 102062 844302 751523 173981 461400 > 4²⁰⁶ [i]
