%I A357389 #6 Sep 26 2022 20:16:08 %S A357389 7,1,736,26048,991434 %N A357389 a(n) is the start of the least run of exactly n consecutive positive integers with strictly increasing values of A071626, or -1 if no such run exists. %C A357389 a(n) is the least number k such that A071626(k) < A071626(k+1) < ... < A071626(k+n-1), but A071626(k-1) >= A071626(k) if k>1 and A071626(k+n-1) >= A071626(k+n). %C A357389 a(6) > 10^7, if it exists. %e A357389 a(1) = 7 since 7 is the least positive integer that does not belong to a run of increasing values of A071626 with a length of at least 2. %e A357389 a(3) = 736 since A071626(735) = A071626(736) = 26 < A071626(737) = 27 < A071626(738) = A071626(739) = 28, and 736 is the least number with this property. %Y A357389 Cf.
