Problem Statement

Let VV be a set of eight points in 3D3\text{D} space that are the vertices of a cube with side length 11. Compute the number of ways we can color the vertices in VV yellow or blue such that
[*] each vertex receives exactly one color, and [/*] [*] there exists a point in 3D3\text{D} space whose distance to each yellow vertex is less than 11 and whose distance to each blue vertex is greater than 11. [/*]
