glide reflection in a sentence

• Its symmetry group is a frieze group generated by a single glide reflection.
• The symmetry operation between sequential vertices is glide reflection.
• The isometry group generated by just a glide reflection is an infinite cyclic group.
• A glide reflection line parallel to a true reflection line already implies this situation.
• Glide reflections are given with dashed lines.
• The transverse articulation ( division ) of the Proarticulata body into "'gliding reflection.
• A glide reflection can be seen as a limiting rotoreflection, where the rotation becomes a translation.
• In 2-dimensions they repeat as glide reflections, as screw axis in 3-dimensions.
• Isometries requiring an odd number of mirrors  reflection and glide reflection  always reverse left and right.
• Some sea pens exhibit glide reflection symmetry, which is rare among non-extinct animals ( see ).
• It's difficult to see glide reflection in a sentence .
• The green bands of illusionary interlace throw off the field pattern's symmetry of reflection and glide reflection.
• This glide reflection is also found in " Spriggina ", another mysterious organism from approximately the same era.
• If there are also true reflection lines in the same direction then they are evenly spaced between the glide reflection lines.
• But left and right halves are organized in an alternating pattern according to glide reflection symmetry rather than bilateral symmetry; thus, these " isomers.
• This is because the conjugate of the translation by a glide reflection is the same as by the corresponding reflection : the translation vector is reflected.
• Lack of known segmented legs or limbs, and glide reflection instead of symmetric segments, suggest an arthropod classification is premature despite some superficial resemblance.
• For any symmetry group containing some glide reflection symmetry, the translation vector of any glide reflection is one half of an element of the translation group.
• For any symmetry group containing some glide reflection symmetry, the translation vector of any glide reflection is one half of an element of the translation group.
• Reflection composed with either of these could cancel down to a single reflection; otherwise it gives the only available three-mirror isometry, a glide reflection.
• Frieze group nr . 6 ( glide-reflections, translations and rotations ) is generated by a glide reflection and a rotation about a point on the line of reflection.
