Notes:
The analysis of the equations vtt=f(x,vx)vxx+g(x,vx) initiated by Ibragimov et al. [J. Math. Phys 32, 2988 (1991)] is continued. The preliminary group classification of these equations with respect to a countable-dimensional subalgebra of their equivalence algebra is presented. This subalgebra is an extension of the 10-dimensional subalgebra considered by Ibragimov et al. The result of the work is a table of nonequivalent equations possessing an additional symmetry.
