What is tesseract definition?

Tesseract is a four-dimensional (4D) analogue of a cube, also known as a hypercube. It is composed of eight cubes of equal size, with all eight cubes meeting at a single point called a vertex. Tesseract represents the dimensions of space and time beyond the three dimensions that humans are accustomed to perceiving. The tesseract has 16 vertices, 32 edges, 24 faces, and eight three-dimensional cubes. It is a geometric shape that is used in physics, mathematics, computer graphics, and other fields to help understand complex concepts related to higher dimensions. The term tesseract was coined by Charles Howard Hinton, an English mathematician, in 1888.
