Query: On conic-line arrangements with nodes, tacnodes, and ordinary triple
  points   In the present paper, we study conic-line arrangements having nodes,
tacnodes, and ordinary triple points as singularities. We provide combinatorial
constraints on such arrangements and we give the complete classification of
free arrangements in this class.
