  1. The distribution of topologies (independent of glycosidic bond conformation and loop lengths) of all 4418 models is reported. The notation here follows Webba da Silva [56]. p, l and d stand for propeller-like, lateral or diagonal loop. Theand + signs refer to anti-clockwise or clockwise rotation of the loop around the G-quadruplex stem, respectively, when the first strand is progressing towards the viewer (see Figure 1).
