	~~In [[geometry]], an '''improper rotation'''~~, ~~also called '''rotoreflection''' or '''rotary reflection'''~~ is~~, depending on context, a~~ [[~~linear transformation~~]] or [[~~affine transformation~~]~~] which~~ is ~~the combination of a~~ [[~~Rotation (geometry)\|rotation~~]] ~~about an axis and~~ a ~~reflection in a plane~~.

	~~In 3D, equivalently it is the combination of a rotation and an~~ [~~[inversion in a point]] on the axis~~. ~~Therefore it is also called a '''rotoinversion''' or '''rotary inversion'''~~.		Feel free to [https://www.rebelmouse.com/shermanwalls/best-nine-tips-for-orgesspill-648799609.html on the internet spilleautomater] visit my web page :: [http://warrenmooretgqn.newsvine.com/_news/2014/08/01/25113558-what-the-pentagon-can-teach-you-about-spill-sikkert-hos-spilleautomaterpnettco Her kan du prøve deg på spilleautomater på nettet]

	~~In both cases the operations commute~~. ~~Rotoreflection and rotoinversion are~~ the ~~same if they differ in [[angle of rotation~~]~~] by 180°, and the point of inversion is in the plane of reflection.~~

	~~An improper rotation of an object thus produces a rotation of its~~ [~~[mirror image]]~~. ~~The axis is called the '''rotation-reflection axis'''~~. ~~This is called an '''''n''-fold improper rotation''' if the angle of rotation is 360°~~/~~''n''. The notation '''''S<sub>n<~~/sub>''''' (''S'' for ''Spiegel'', German for [[mirror]]) denotes the symmetry group generated by an ''n''-fold improper rotation (not to be confused with the same notation for [[symmetric group]]s). The notation <math>\bar{n}</~~math> is used for '''''n''-fold rotoinversion''', i.e. rotation by an angle of rotation of 360°~~/~~''n'' with inversion.~~

	~~In a wider sense, an "improper rotation" may be defined as any '''[[Euclidean group#Direct and indirect isometries\|indirect isometry]]''', i.e., an element of ''E''(3)\''E''<sup>+<~~/sup>(3) (see [[Euclidean group]]): thus it can also be a pure reflection in a plane, or have a [[glide reflection\|glide plane]]. An indirect isometry is an [[affine transformation]] with an [[orthogonal matrix]] that has a determinant of −1.

	~~A '''proper rotation''' is an ordinary rotation. In~~ the ~~wider sense, a "proper rotation" is defined as a '''direct isometry''', i.e., an element of ''E''<sup>+</sup>(3): it~~ can ~~also be the identity, a rotation with a translation along the axis, or a pure translation. A direct isometry is an affine transformation with an orthogonal matrix that has a determinant of 1.~~

	~~In either the narrower or the wider senses, the composition of two improper rotations is a proper rotation, and the composition of an improper and a proper rotation is an improper rotation.~~

	When studying the symmetry of a physical system under an improper rotation (e.g., if a system has a mirror symmetry plane), it is important to distinguish between [[vector (geometry)\|vector]]s and [[pseudovector]]s (as well as [[scalar (mathematics)\|scalars]] and [[pseudoscalar (mathematics)\|pseudoscalar]]s, and in general; between [[tensor]]s and [[pseudotensor]]s), since the latter transform differently under proper and improper rotations (in 3 dimensions, pseudovectors are invariant under inversion).
