Now we methodically start labeling vertices by beginning with the vertices of degree 3 and marking a and b. Label Odd Vertices WebIt is common for people to refer briefly though inaccurately to an ordered set as an order , to a totally ordered set as a total order , and to a partially ordered set as a partial order . It is usually clear by context whether "order" refers literally to an order (an order relation) or by synecdoche to an ordered set . Examples:
