             (n2:Node),
             (n3:Node),
             (n0)-[:EDGE]->(n1),
             (n1)-[:EDGE]->(n2),
             (n2)-[:EDGE]->(n3)
      """
    When executing query:
      """
      MATCH ()-[r:EDGE]-()
      MATCH p = (n)-[*0..1]-()-[r]-()-[*0..1]-(m)
      RETURN count(p) AS c
      """
