Combining two equal glide plane operations gives a pure translation with a translation vector that is twice that of the glide reflection, so the even powers of the glide reflection form a translation group. In the case of glide-reflection symmetry, the symmetry group of an object contains a glide reflection and the group generated by it. For ...
Communication Theory is a quarterly peer-reviewed academic journal publishing research articles, theoretical essays, and reviews on topics of broad theoretical interest from across the range of communication studies. It was established in 1991 and the current editor-in-chief is Thomas Hanitzsch (University of Munich).
p2mm: TRHVG (translation, 180° rotation, horizontal line reflection, vertical line reflection, and glide reflection) Formally, a frieze group is a class of infinite discrete symmetry groups of patterns on a strip (infinitely wide rectangle), hence a class of groups of isometries of the plane, or of a strip.
[d q] Glide reflection; Three mirrors. If they are all parallel, the effect is the same as a single mirror (slide a pair to cancel the third). Otherwise we can find an equivalent arrangement where two are parallel and the third is perpendicular to them. The effect is a reflection combined with a translation parallel to the mirror.
Since the introduction of co-cultural theory in "Laying the foundation for co-cultural communication theory: An inductive approach to studying "non-dominant" communication strategies and the factors that influence them" (1996), Orbe has published two works describing the theory and its use as well as several studies on communication patterns and strategies based on different co-cultural groups.

In group theory and geometry, a reflection group is a discrete group which is generated by a set of reflections of a finite-dimensional Euclidean space. The symmetry group of a regular polytope or of a tiling of the Euclidean space by congruent copies of a regular polytope is necessarily a reflection group.
The second part introduces the definitions of reflection systems and reflection groups, the special case of dihedral groups, and root systems. [2] [3] Part III of the book concerns Coxeter complexes, and uses them as the basis for some group theory of reflection groups, including their length functions and parabolic subgroups.
