Errors[edit]

The article is not about symmetry in mathematics. It is about symmetric functions with respect to permutation of arguments. The first section gives a definition, next sections are just examples of symmetric functions.

In particular section "in geometry" is an example of symmetric function of three cartesian coordinates, but it is not the definition of a symmetry in geometry. For example reflection against line y=5x+2 is not a symmetry according to this section.

Section "Symmetry in probability theory" is a bit strange as well. For example normal distribution is called symmetric distribution, but according to this section and "Randomness" section it is not symmetric. Well, normal distribution is not an example of symmetry with respect to permutation.

The only thing not connected to the symmetric functions is the first sentence, which states, the article is about something defined in the other article. Best, Olaf (talk) 21:30, 5 September 2009 (UTC)
