No, six-dimensional space is an abstract concept related to geometry and physics. Usually refers to the six-dimensional Euclidean space, that is, the space composed of six coordinate axes. In this space, each point can be represented by six coordinates. Calabi-Qiu Chengtong space is a mathematical concept, which refers to a high-dimensional space with a specific geometric shape. It was put forward by mathematicians Calabi and Qiu Chengtong in 1980s to describe some problems in physics and mathematics. Calabi-Qiu Chengtong space can have different dimensions, not necessarily six dimensions.
