论文摘要
我们介绍了一个大型组合物体，称为标准难题，由非常简单的规则定义。我们专注于可以通过明确的公式或经典数字来解决枚举问题的标准难题，例如二项式系数，斐波那契数字，切线号，加泰罗尼亚语号码，$ \ ldots $
We introduce a large family of combinatorial objects, called standard puzzles, defined by very simple rules. We focus on the standard puzzles for which the enumeration problems can be solved by explicit formulas or by classical numbers, such as binomial coefficients, Fibonacci numbers, tangent numbers, Catalan numbers, $\ldots$
