(241−128, 241, 1469)-Net in Base 4 — Upper bound on s

There is no (113, 241, 1470)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 12 868795 204922 657532 906257 142938 081004 215369 426403 697235 020236 435224 439352 218499 666383 948128 584994 072727 175949 012064 308462 902668 426369 635927 176030 > 4²⁴¹ [i]
