A240823
a(n) = index of first nonexisting term of the meta-Fibonacci sequence {f(k) = k for k <= n; f(k)=f(k-f(k-2))+f(k-f(k-n))} if that sequence is only defined for finitely many terms, or 0 if that sequence is infinite.

COMMENTS
a(4)=0 and a(8)=0 are only conjectures.
Except for the zero entries, this is equal to A240819(n)+1. See that entry for further information.
