Triads in the triad census41 with transitive semicycles. Signs of edges (not shown in the figure) can either be positive or negative. Triad types are labeled based on the number of mutual (first digit), asymmetric (second digit), and null (third digit) dyads, and an additional letter for direction (T: transitive, D: down, U: up). See41 for more details about nomenclature for the triad census.
