We study nontrivial deformations of the natural action of the Lie superalgebra K(1) of contact vector elds on the (1; 1)-dimensional superspace R1j1 on the space of symbols e Sn = Ln k=0 F�´������k2 . We calculate obstructions for integrability of in nitesimal multiparameter deformations and determine the complete local commutative algebra corresponding to the miniversal deformation.
