Proof step 3 from proof abs-nodes-inv-flashsize-h (previous step)

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)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 4:
# 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)

Rule argument

Additional information

Used simplifier rules: abs-nodes-elems-adr-length-h: ⊦ abs-nodes(buf, m, gndx, lax, weak) → # gndx = # lax; (forward) from specification abs-list[encoding-group-node]
