%N A059774 Consider the line segment in R^n from the origin to the point P=(1,2,
               3,...,n); let d = squared distance to this line from the closest 
               point of Z^n (excluding the endpoints). Sequence gives d times P.P.
%C A059774 P.P is given by A000330(n). For n >= 10, a(n) = A000330(n-1).
%C A059774 Officially these are just conjectures so far.
