[en] The Pascal triangle and the corresponding Sierpinski gasket are well-studied objects. They exhibit self-similarity features and have connections with dynamical systems, cellular automata, number theory and automatic sequences in combinatorics on words. In this talk, the first step is to recall the well-known link between those two objects. Then this link is exploited to define Pascal-like triangles associated with different numeration systems. Those new objects converge to analogues of the Sierpinski gasket. If time permits, other questions will be discussed.
