about "Betti number"
I think the example is lack of explanations. Because, firstly the orientation on the 1- and 2- simplex's should be introduced and the boundary map should be neatly defined on them and then we will be able to compute the Betti numbers, the rank of their homology groups.--Enyokoyama (talk) 10:40, 13 March 2014 (UTC)
