Comments

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).

Examples

			a(2) = 64 since A071626(64) = 9 > A071626(65) = 8, and A071626(63) = A071626(66) = 9, and 64 is the least number with this property.
