The case of small parameter. This is the second paper in the cycle of papers about the $BV$-structure on the Hocshild cohomology of exceptional algebras of quaternion type. The full description of the $BV$-structure is given for the case of algebras $R(k,0,d)$ of quaternion type, defined by parameter $k = 2$ according to the Erdmann classification.
