A hypercube, also known as a tesseract, is a geometric shape with four dimensions. Other synonyms for a hypercube include a four-dimensional cube, a 4-cube, a 4-hypercube, or a fourth-order hypercube. The hypercube is a fascinating object in mathematics and has been explored in science fiction, art, and philosophy for decades. The shape is a significant concept in higher-dimensional geometry and has been used to visualize complex mathematical concepts. Synonyms such as 4-cube or 4-hypercube emphasize the four-dimensional nature of the shape, while terms like tesseract and fourth-order hypercube stress the importance of its position in geometry.
