***** To join INSNA, visit http://www.insna.org ***** Dear all, I'm looking for and algorithm to count the number of realizations of a particular triad type (http://goo.gl/4l77m); more formally, I need to count labeled triads isomorphic to a given unlabeled one. As an example, for triad 012 there are six realizations of the asymmetric dyad and for triad 102 there are three realizations of the mutual dyad. Number of realizations of the remaining triads are easily counted with the pencil & paper approach. The table below reports number of realizations for each particular triad type (http://goo.gl/4l77m). 003 (1) 012 (6) 102 (3) 021D (3) 021U (3) 021C (6) 111D (6) 111U (6) 030T (6) 030C (2) 201 (3) 120D (3) 120U (3) 120C (6) 210 (6) 300 (1) Any pointers would be greatly appreciated, Andrej _____________________________________________________________________ SOCNET is a service of INSNA, the professional association for social network researchers (http://www.insna.org).
