TS — a total point symbol for net summarizes all the point symbols for the non-equivalent nodes with their relation/weight.
Node — number of nodes.
CS — coordination sequence {Nk}, k=1—n, is a sequence of numbers N1, N2, N3,... counting the atoms in the 1st, 2nd, 3rd etc. coordination shells of any given atom in the net.
ES — extended point symbol lists all shortest circuits for each angle for any non-equivalent atom.
VS — vertex symbol gives similar information as ES, but only for rings (circuits without shortcuts).
