Given lines $m$ and $n$ which are distinct, and planes $α$ and $β$ which do not coincide, consider the following statements:
1. If line $m$ is parallel to plane $α$, then $m$ is parallel to the countless lines in plane $α$.
2. If plane $α$ is parallel to plane $β$, and line $m$ is contained in plane $α$ while line $n$ is contained in plane $β$, then $m$ is parallel to $n$.
3. If line $m$ is perpendicular to plane $α$, and line $n$ is perpendicular to plane $β$, and if $m$ is parallel to $n$, then plane $α$ is parallel to plane $β$.
4. If plane $α$ is parallel to plane $β$, and line $m$ is contained in plane $α$, then $m$ is parallel to plane $β$.

Among the above statements, the sequence numbers of the true propositions are ____ (list all the sequence numbers of the true propositions).
