(100, 100+148, 925)-Net in Base 4 — Upper bound on s

There is no (100, 248, 926)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 212140 812996 047993 020241 451704 626506 450240 651685 767265 931537 741928 625715 893136 741170 203631 256567 414181 428728 144116 749623 372053 593741 873805 033068 026468 > 4²⁴⁸ [i]
