# Repeated (..)

 p.. or Repeated[p]is a pattern object which represents a sequence of one or more expressions, each matching p. Repeated[p, max] represents up to max expressions matching p. Repeated[p, {min, max}] represents between min and max expressions matching p. Repeated[p, {n}] represents exactly n expressions matching p.
• p.. can appear as an argument of any function. It represents any sequence of arguments.
• All the objects in the sequence represented by p.. must match p, but the objects need not be identical.
• The expression p may, but need not, itself be a pattern object.
