sextuple

This term is primarily used in technical, mathematical, or financial contexts to describe a precise six-fold increase or composition. It carries a tone of significant growth or complexity, often appearing in reports to emphasize a dramatic scale of expansion compared to more common terms like double or triple.

As a noun, it refers to a set of six, though it is far less common than its adjective and verb forms. In most natural English contexts, speakers prefer using "six times" or "six-fold" unless they are aiming for a specific formal or numerical precision.
