Knowledge about combinatorics, fractals, generation of form, graph theory, nested patterns, recursion, representations of numbers, short programs and tilingThe Delannoy number D(x, y) gives the number of ways to reach point {x, y} (with non-negative integer coordinates) from the origin using only certain moves. They may be either up {0, 1}, to the right {1, 0} or one step along the diagonal {1, 1}. Plots of D (x, y) mod n show nested fractal patternsComponente Curricular::Ensino Médio::Matemática
