✦ Synopsis

Nature of physical problem versity of Belfast, N. Ireland (see application form in this issue) Lie-Bäcklund symmetries are the wide generalization of point and contact Lie symmetries and essentially extend the applica-Computer: IBM 360/370 tions of the group theoretical methods in mathematical physics. Restrictions on the complexityproblem Operating system: OS In most cases the available computer memory is the Severest restriction. It may only be avoided if the problem is split into Programming language used: PL/1 several smaller ones. High speedstorage required: depends on the problem, minimum Running time about 200000 bytes

It depends heavily on the number of dependent and independent variables, the order of equations and the order of de-No.
