(166, 166+54, 293040)-Net in Base 4 — Upper bound on s

There is no (166, 220, 293041)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 2 839473 495066 875765 468187 356967 986026 153354 707236 292420 964550 298711 058752 017362 989595 027182 974302 237178 372826 454644 289290 134468 294752 > 4²²⁰ [i]
