There is the algebraic expression a+b+c. If we replace under the rule {a->b, b->c, c->a}, the expression is left unchanged. But for expressions like 2a+b+c, the replacement will change the expression. What is the word to describe this kind of symmetry? Thanks

  • Is there any term in English? Or you are looking for an algebraic jargon?

    If f(x,y,z) = f(y,z,x), then f(x,y,z) is a cyclic expression. Mar 15, 2014 at 17:03
  • @DamkerngT. - I think you should make that an answer, because I think that is the answer.

  • @StoneyB - I just checked the help pages at the Mathematics, and I don't think this question would be a good fit for their site. It doesn't seem like it would be on-topic there.

The term for it is Cyclic Expressions.

I just found a good page that explains Symmetric and Cyclic Expressions. According to the page,

An expression f(x,y,z) is said to be a cyclic expression if f(x,y,z) = f(y,z,x).
