Proof step 4 from proof abs-nodes-inv-flashsize-h (previous step)

# gndx = # lax, abs-nodes(buf, m, gndx, lax, weak), ∀ buf0, m, gndx, lax, weak. # buf0 < # buf → abs-nodes(buf0, m, gndx, lax, weak) → inv-flashsize(gndx, lax) ⊦ inv-flashsize(gndx, lax)

User applied rule constructor cut

And obtained the following new goals

Proof step 5:
# gndx = # lax, gndx = gnd + gndx0, abs-nodes(buf, m, gndx, lax, weak), ∀ buf0, m, gndx, lax, weak. # buf0 < # buf → abs-nodes(buf0, m, gndx, lax, weak) → inv-flashsize(gndx, lax) ⊦ inv-flashsize(gndx, lax)

Rule argument

var: gndx

Additional information

Used simplifier rules: group-node-list freely generated by [], +;;% ⊦ # [] = 0; (s)% ⊦ # lax = 0 ↔ lax = []; (s)% ⊦ inv-flashsize([], lax) ↔ lax = []; (s)
