(42, 42+106, 1157)-Net in Base 9 — Upper bound on s

There is no (42, 148, 1158)-net in base 9, because

the generalized Rao bound for nets shows that 9^mÂ â‰¥ 1753 585351 750527 559735 222051 502383 423710 011487 245562 851557 119198 023489 412006 126480 571980 369841 723010 766175 473515 926976 515441 109280 670778 663025 > 9¹⁴⁸ [i]
