Throughout this paper the actions of groups on graphs with inversions areallowed. An element g of a group \(G\) is called inverter if there exists a tree\(X\) where \(G\) acts such that \(g\) transfers an edge of \(X\) into its inverse.\(A\) group \(G\) is called accessible if \(G\) is finitely gene...
