Hi Gerardo, I’m guessing that it’s considered a basic origami molecule, as it appears in many different origami models in one form or another, from roses and tessellations to the center of stars made from bird bases. In other words, I don’t think you need to ask anyone’s authorization, although I may be wrong of course. Matthew
