A first category deals with a hyperincursive generator based on a composition rule applied to a defined path in the frame. A second category of algorithms is based on a recursive generator obeying certain symmetries. This paper will consider generalised Sierpinski fractals generated by modulo 2 and modulo 3. Even and odd modulo give rise to very different properties of symmetry. Tue, 18 Jun 2024 16:40:48 +0200 Tue, 18 Jun 2024 16:41:02 +0200 http://popups.lib.uliege.be/1373-5411/index.php?id=156
