(60, 60+136, 420)-Net in Base 4 — Upper bound on s

There is no (60, 196, 421)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 11247 506814 638554 385962 381830 543153 885566 253722 059377 844892 540412 156181 219936 741911 820366 982111 173839 755329 014802 606390 > 4¹⁹⁶ [i]
