BMS algebra in three spacetime dimensions can be deformed into a twoparameter family of algebra known as $W(a,b)$ algebra. For $a=0$, we show thatother than $W(0,-1)$, no other $W(0,b)$ algebra admits a non-degeneratebilinear and thus one can not have a Chern-Simons gauge theory formulation withthem. However, they may appear in a three-dimensional gravity description,where we also need to have a spin 2 generator, that comes from the $(a=0,b=-1)$sector. In the present work, we have demonstrated that the asymptotic symmetryalgebra of a spin 3 gravity theory on flat spacetime has both the $W(0,-1)$ and$W(0,-2)$ algebras as subalgebras. We have also constructed a dual boundaryfield theory for this higher spin gravity theory by using theChern-Simons/Wess-Zumino-Witten correspondence.
