I read the wikipedia article on combinations and saw two drawings there

http://en.wikipedia.org/wiki/File:Combinations_without_repetition;_5_choose_3.svg

http://en.wikipedia.org/wiki/File:Combinations_with_repetition;_5_multichoose_3.svg

and I am asking myself whats the points of them, does they make something easier to comprehend. Yes there is a pattern, but some pattern must arise, its not so that this pattern makes something easier. For me a textual description of how to generate all combinations is far more easier to understand. Or are these type of diagrams some special diagrams used in combinatorics?

    I think it's just different strokes for different folks. Some people find textual descriptions easier to understand, some, pictorial. If it doesn't work for you, ignore it and stick with what does work for you.2012-11-12

    For the left-hand pictures, spot that the top picture appears at the end of the bottom picture.2012-11-12
