Combinatorial topology is a subset of algebraic topology  that uses combinatorial  methods. For
 example, simplicial homology  is a combinatorial
 construction in algebraic topology , so it belongs
 to combinatorial topology.
Algebraic topology  originated with combinatorial topology, but went beyond it probably for the first time in the 1930s when Čech
 cohomology  was developed.
