(90, 90+96, 1305)-Net in Base 4 — Upper bound on s

There is no (90, 186, 1306)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 9717 505684 520965 438870 160665 890723 136984 835543 120431 737796 745108 479267 333694 567972 838132 678187 578594 575819 232760 > 4¹⁸⁶ [i]
