(86, 86+162, 654)-Net in Base 4 — Upper bound on s

There is no (86, 248, 655)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 206262 529664 298783 975725 616707 859077 913112 008355 244964 839450 257900 471617 170737 173370 842430 619828 371753 624411 060841 777120 576396 480147 477834 654514 810832 > 4²⁴⁸ [i]
