Proof step 16:

Proof step 18:
adP0(a, d)(H1), ((adP0 ⊗_ st0))(H0), ((adP ⊗_ st0))(H0), H1 ⊥ H0, ∀ a0, H. a0 ∈ st0[a, d] ∧ adP0(a0, st0[a, d][a0])(H) → adP(a0, st0[a, d][a0])(H), ∀ st1, adP0, H, adP. # st1 < # st0[a, d] → ((adP0 ⊗_ st1))(H) ∧ (∀ a, H. a ∈ st1 ∧ adP0(a, st1[a])(H) → adP(a, st1[a])(H)) → ((adP ⊗_ st1))(H) ⊦ ((adP(a, d) * adP ⊗_ st0))(H1 ∪ H0), a ∈ st0, adP(a, d)(H1) ∧ ((adP ⊗_ st0))(H0)

Rule argument

subst: [st1, adP0, H, adP] → [st0, adP0, H0, adP]
