  5. Seven-dimensional space - Wikipedia

    en.wikipedia.org/wiki/Seven-dimensional_space

    When n = 7, the set of all such locations is called 7-dimensional space. Often such a space is studied as a vector space , without any notion of distance. Seven-dimensional Euclidean space is seven-dimensional space equipped with a Euclidean metric , which is defined by the dot product .

  6. Seven-dimensional cross product - Wikipedia

    en.wikipedia.org/wiki/Seven-dimensional_cross...

    A cross product on a Euclidean space V is a bilinear map from V × V to V, mapping vectors x and y in V to another vector x × y also in V, where x × y has the properties [1] [6] orthogonality : x ⋅ ( x × y ) = ( x × y ) ⋅ y = 0 , {\displaystyle \mathbf {x} \cdot (\mathbf {x} \times \mathbf {y} )=(\mathbf {x} \times \mathbf {y} )\cdot ...

    The V-Cube 7 is a combination puzzle in the form of a 7×7×7 cube. The first mass-produced 7×7×7 was invented by Panagiotis Verdes and is produced by the Greek company Verdes Innovations SA. Other such puzzles have since been introduced by a number of Chinese companies, [ 1 ] some of which have mechanisms which improve on the original.

  9. Voigt notation - Wikipedia

    en.wikipedia.org/wiki/Voigt_notation

    In mathematics, Voigt notation or Voigt form in multilinear algebra is a way to represent a symmetric tensor by reducing its order. [1] There are a few variants and associated names for this idea: Mandel notation, Mandel–Voigt notation and Nye notation are others found.
