English expression for strung together equalities or inequalities (i.e. $a = \dots = z$ or $a < \dots < z$)? German: "(Un-)Gleichungskette"

Question

Is there a standard expression for strung together equalities/inequalities in English?

What I mean is $a = b = \cdots = z$ or $a < b < \cdots< z$.

In German, I find the words Gleichungskette (equality chain) and Ungleichungskette (inequality chain) useful when talking and writing about math. In English, do we just refer to the whole thing as "the equality"/"the inequality" when referring to the whole chain?

Possibilities:

• equality chain
• chain of equalities
• equality string
• string of equalities
• others?
