(240−136, 240, 1107)-Net in Base 4 — Upper bound on s

There is no (104, 240, 1108)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 3 259798 436481 430472 608502 659206 724446 995788 679697 876440 453664 020682 887151 958340 779657 829667 049465 776311 656532 598488 454367 517804 030669 883073 145380 > 4²⁴⁰ [i]
