Abstract

百度 2014年2月，习近平总书记在全国省部级主要领导干部学习贯彻十八届三中全会精神全面深化改革专题研讨班上，曾引用了唐太宗的一句话“治国犹如栽树，本根不摇则枝叶茂荣”，强调治理国家，制度是起根本性、全局性、长远性的作用。

Let $s(n)$ be the side of the smallest square into which we can pack n unit squares. We present a history of this problem, and give the best known upper and lower bounds for $s(n)$ for $n\le100$, including the best known packings. We also give relatively simple proofs for the values of $s(n)$ when $n = 2$, 3, 5, 8, 15, 24, and 35, and more complicated proofs for $n=7$ and 14. We also prove many other lower bounds for various $s(n)$.
