I'm just unable to see how this could be correct, if someone can take a look it would be much appreciated.

sum((piecewise(6 = k, 1, 6 <> k, 0)-3*frac((1/3)*N)*piecewise(6 = k+1, 1, 6 <> k+1, 0))*floor((1/3)*N*3^(k-floor(ln((1/3)*N)/ln(3))-1)), k = 1 .. floor(ln((1/3)*N)/ln(3))+1)

sum((piecewise(6 = k, 1, 6 <> k, 0)-3*frac((1/3)*N)*piecewise(6 = k+1, 1, 6 <> k+1, 0))*floor((1/3)*N*3^(k-floor(ln((1/3)*N)/ln(3))-1)), k = 1 .. floor(ln((1/3)*N)/ln(3))+1)
