Nuprl Lemma : partition-refines_transitivity
∀I:Interval. ∀P,Q,R:partition(I).  (P refines Q 
⇒ Q refines R 
⇒ P refines R) supposing icompact(I)
Proof
Definitions occuring in Statement : 
partition-refines: P refines Q
, 
partition: partition(I)
, 
icompact: icompact(I)
, 
interval: Interval
, 
uimplies: b supposing a
, 
all: ∀x:A. B[x]
, 
implies: P 
⇒ Q
Definitions unfolded in proof : 
partition-refines: P refines Q
, 
all: ∀x:A. B[x]
, 
uimplies: b supposing a
, 
implies: P 
⇒ Q
, 
uall: ∀[x:A]. B[x]
, 
member: t ∈ T
