The fundamental group of \(X\) at \(x_0\) is \[\pi_1(X, x_0) \;:=\; \bigl\{[\gamma] \mid \gamma \text{ is a loop based at } x_0\bigr\}\] equipped with the group operation of concatenation: \[[\gamma] \cdot [\delta] := [\gamma * \delta], \qquad (\gamma * \delta)(s) := \begin{cases} \gamma(2s) & s \in [0,\tfrac{1}{2}] \\ \delta(2s-1) & s \in [\tfrac{1}{2},1] \end{cases}\] The identity element is the class of the constant loop \([c_{x_0}]\), and the inverse of \([\gamma]\) is \([\bar\gamma]\) where \(\bar\gamma(s) := \gamma(1-s)\).

This is complicated by growing measures of regulation from countries around the world.

Domestically, 32 states have introduced age verification legislation, and that is only intensified in externalities that are yet to be seen after the Federal Trade Commission announced last week it would exercise “enforcement discretion” regarding the Children’s Online Privacy Protection Rule (COPPA). This would allow social media companies to collect children’s data without parental consent—but solely for age verification purposes.，更多细节参见体育直播
