The algorithm of calculation of isotropy algebras of equations $y''=a(x,y)y'\,^3+b(x,y)y'\,^2+c(x,y)y'+d(x,y)$,


The action of pseudogroup of all point transformations of variables $x$, $y$ in the natural bundle of
ordinary differential equations  $y''=a(x,y)y'\,^3+b(x,y)y'\,^2+c(x,y)y'+d(x,y)$  is extended to the action 
on the bundle of $k$\-/jets of sections of this bundle. In this paper,it is represented the code of the 
computer algebraic system REDUCE to calculate isotropy algebras of this action.
