    0 references
    The author presents ring generators for the invariants of the group \(H\) generated by reflections and satisfying the following condition: the \(H\)-orbits of symmetry directions of this group are infinite and their linear hulls form three planes with pairwise zero intersections. Conditions under which the ring of invariants of the group \(H\) is not free are given.
