Proof step 3 from proof abs-log-append-one (previous step)

gstore[n] = groupblock(gndx, lax, m), ∀ gstore, n, gndx, lax, m. gstore[n] = groupblock(gndx, lax, m) → abs-log(nx0 + n ', gstore) = abs-log(nx0, gstore) + lax.to-adr(n) ⊦ abs-log((lnum + nx0) + n ', gstore) = abs-log(lnum + nx0, gstore) + lax.to-adr(n)

Proof step 4:
gstore[n] = groupblock(gndx, lax, m), ∀ gstore, n, gndx, lax, m. gstore[n] = groupblock(gndx, lax, m) → abs-log(nx0 + n ', gstore) = abs-log(nx0, gstore) + lax.to-adr(n) ⊦ abs-log(nx0 + n ', gstore) = abs-log(nx0, gstore) + lax.to-adr(n)
