_topol_node.extended_point_symbol

Definition:

   
    The extended point symbol of a N-coordinated node lists all shortest
    circuits for each of the N(N-1)/2 angles (pairs of edges) incident to
    the node. It is written as A(a).B(b)... where A, B, ... designate sizes of
    circuits, which meet at angles A, B, ..., and a, b, ... designate numbers
    of these circuits. It is sorted so shortest circuits come first. For
    a 4-coordinated node connected to nodes w,x,y,z, the angles are ordered
    in opposite pairs; wx,yz; wy,xz; wz,xy (written in lexicographic order
    smallest numbers first).
