Details of the hypergraph:
Center hyperedge (induced by source paper "2 edge twinless blocks"):
  Abstract: Let $G=(V,E))$ be a directed graph. A $2$-edge-twinless block in $G$ is a maximal vertex set $C^{t}\subseteq V$ of with $|C^{t}|>1$ such that for any distinct vertices $v,w \in C^{t}$, and for every edge $e\in E$, the vertices $v,w$ are in the same twinless strongly connected component of $G\setminus\left \lbrace e \right\rbrace $. An edge $e$ in a twinless strongly connected graph is a twinless bridge if the subgraph obtained from $G$ by removing $e$ is not twinless strongly connected. #R##N#In this paper we show that the $2$-edge-twinless blocks of $G$ can be computed in $O((b_{t}n+m)n)$ time, where $b_{t}$ is the number of twinless bridges of $G$.
