FORMULA

3/2 = 1+ph^2*(1+ph^3+ph^6+ph^9+ph^12+...). - Joerg Arndt, Mar 04 2010

a(n) = (1/9)*(4*((n-1) mod 3)-2*(n mod 3)+((n+1) mod 3))+(C(2*(n-1),n-1) mod 2). [Paolo P. Lava, Mar 15 2010]

G.f.: x*(1+x^2-x^3)/(1-x^3). [Bruno Berselli, Apr 06 2012]

a(n) = A079978(n) with n>1, a(1)=1. [Bruno Berselli, Apr 06 2012]
