FORMULA

a(n) = A000045(A182601).
a(n) = min{ A000045(i): A000045(j) in A002808 for all j=i..i+n1}.


EXAMPLE

a(2) = a(3) = 21 because (21, 34, 55) is a run of three consecutive Fibonacci composites, so 21 is in the sequence (21, 34) of at least 2 and in the sequence (21, 34, 55) of at least 3 consecutive composites in A000045.
