FORMULA
| a(n)=(1/30)*{26*(n mod 6)+[(n+1) mod 6]+[(n+2) mod 6]+6*[(n+3) mod 6]+[(n+4) mod 6]+[(n+5) mod 6]}, with n>=0. - Paolo P. Lava (paoloplava(AT)gmail.com), Nov 19 2007
a(n) = 3-2*cos(Pi*n/3)/3 -2*sin(Pi*n/3)/sqrt(3) -cos(2*Pi*n/3) -sin(2*Pi*n/3)/sqrt(3) -(-1)^n/3. - R. J. Mathar, Oct 08 2011
