Description: A lattice dilation is an automorphism. (Contributed by NM, 20-May-2012.)
Hypotheses
Ref Expression
ldillaut.h 𝐻 = (LHyp‘𝐾)
ldillaut.i 𝐼 = (LAut‘𝐾)
ldillaut.d 𝐷 = ((LDil‘𝐾)‘𝑊)
Assertion
Ref Expression
ldillaut (((𝐾𝑉𝑊𝐻) ∧ 𝐹𝐷) → 𝐹𝐼)

Proof of Theorem ldillaut
Dummy variable 𝑥 is distinct from all other variables.
