Consider the line segment in R^n from the origin to the point v=(2,3,5,7,11,...) with prime coordinates; let d = squared distance to this line from the closest point of Z^n (excluding the endpoints). Sequence gives d times v.v. |

v.v is given by A024450(n). For n >= 19, a(n) = A024450(n-1).
Officially these are just conjectures so far.
