(222−102, 222, 2721)-Net in Base 4 — Upper bound on s

There is no (120, 222, 2722)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 45 607645 145207 772082 205905 405091 410906 485165 657305 061633 833881 715917 409914 724948 791248 759499 972146 813376 035030 172079 198486 908373 210560 > 4²²² [i]
