Query: Infinite series solutions of the symmetry equation for the $1 +2$
  dimensional continuous Toda chain   A sequence of solutions to the equation of symmetry for the continuous Toda
chain in $1+2$ dimensions is represented in explicit form. This fact leads to
the supposition that this equation is completely integrable.
