# Reiteration
 | 
						|
 | 
						|
**Reiteration (R)** allows us to restate any proposition already in the proof within the main proof or a more deeply nested sub-proof. Reiteration allows us to reuse any assumptions, or propositions derived from assumptions, without having to introduce a new dependency with another assumption.
