Trail is an open walk in which no edge is repeated. Vertex can be repeated. 3. Circuit –. Traversing a graph such that not an edge is repeated but vertex can be repeated and it is closed also i.e. it is a closed trail. Vertex can be repeated. Edge can not be repeated. Here 1->2->4->3->6->8->3->1 is a circuit.
