In geometry, a tesseract or 4-cube is a four-dimensional hypercube, analogous to a two-dimensional square and a three-dimensional cube. [1] Just as the perimeter of the square consists of four edges and the surface of the cube consists of six square faces, the hypersurface of the tesseract consists of eight cubical cells, meeting at right angles.

In geometry, a hypercube is an n-dimensional analogue of a square (n = 2) and a cube (n = 3); the special case for n = 4 is known as a tesseract.It is a closed, compact, convex figure whose 1-skeleton consists of groups of opposite parallel line segments aligned in each of the space's dimensions, perpendicular to each other and of the same length.
The Fourth Dimension (4D) was a major video game publisher for the BBC Micro, Acorn Electron, Acorn Archimedes and RiscPC between 1989 and 1998. Previously, The Fourth Dimension had been known as Impact Software , which specialised mainly in BBC Micro games.
Four-dimensional space (4D) is the mathematical extension of the concept of three-dimensional space (3D). Three-dimensional space is the simplest possible abstraction of the observation that one needs only three numbers, called dimensions, to describe the sizes or locations of objects in the everyday world.
The algorithm embeds edge-disjoint binomial trees in the hypercube, such that each neighbor of processing element is the root of a spanning binomial tree on nodes. To broadcast a message, the source node splits its message into k {\displaystyle k} chunks of equal size and cyclically sends them to the roots of the binomial trees.
Fred Hemmings reviewed the original self-published version of Fourth Dimension for White Dwarf #3, giving it an overall rating of 7 out of 10, and stated that "unless you can't stand purely cerebral games I would recommend the purchase of 4D." [3] Andy Davis reviewed 4th Dimension in The Space Gamer No. 35. [1]
The odd-dimensional rotation groups do not contain the central inversion and are simple groups. The even-dimensional rotation groups do contain the central inversion −I and have the group C 2 = {I, −I} as their centre. For even n ≥ 6, SO(n) is almost simple in that the factor group SO(n)/C 2 of SO(n) by its centre is a simple group.
