&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;&amp;#039;&amp;#039;&amp;#039;Configuration space&amp;#039;&amp;#039;&amp;#039;  Given a topological space &amp;lt;math&amp;gt;X&amp;lt;/math&amp;gt;, the &amp;lt;math&amp;gt;n&amp;lt;/math&amp;gt;th ordered configuration space of &amp;lt;math&amp;gt;X&amp;lt;/math&amp;gt; denoted by &amp;lt;math&amp;gt;\mathrm{Conf}_n(X)&amp;lt;/math&amp;gt; is the set of &amp;lt;math&amp;gt;n&amp;lt;/math&amp;gt;-tuples of pairwise  distinct points in &amp;lt;math&amp;gt;X&amp;lt;/math&amp;gt;, that is &amp;lt;math&amp;gt;\mathrm{Conf}_n(X):= \prod^n X \setminus \{(x_1, \ldots, x_n) : x_i = x_j \;\mathrm{for} \;i\ne j\}&amp;lt;/math&amp;gt;.&lt;br /&gt;

&lt;br /&gt;
In physics, parameters are used to define the configuration of a system and the vector space defined by these parameters is the configuration space of the system. It is used to describe the state of a whole system as a single point in a higher-dimensional space.&lt;br /&gt;
&lt;br /&gt;
&amp;#039;&amp;#039;&amp;#039;Examples of Configuration space&amp;#039;&amp;#039;&amp;#039;&lt;br /&gt;
&lt;br /&gt;
1. The configuration space of a particle in &amp;lt;math&amp;gt;\mathbb{R}^3&amp;lt;/math&amp;gt; is &amp;lt;math&amp;gt;\mathbb{R}^3&amp;lt;/math&amp;gt;. For &amp;lt;math&amp;gt;n&amp;lt;/math&amp;gt; particles in &amp;lt;math&amp;gt;\mathbb{R}^3&amp;lt;/math&amp;gt;, it is &amp;lt;math&amp;gt;\mathbb{R}^{3n}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
2. For a rigid body in &amp;lt;math&amp;gt;\mathbb{R}^3&amp;lt;/math&amp;gt;, the configuration space is &amp;lt;math&amp;gt;\mathbb{R}^3 \times SO(3)&amp;lt;/math&amp;gt;. Generally, it is &amp;lt;math&amp;gt;\mathbb{R}^n \times SO(n)&amp;lt;/math&amp;gt;, where &amp;lt;math&amp;gt;SO(n)&amp;lt;/math&amp;gt; is the special orthogonal group.&lt;/div&gt;</summary>
