Q is empty.
Special symbols used for the transformation (see [GM04]):
top: top_1, active: active_1, mark: mark_1, ok: ok_1, proper: proper_1
The replacement map contains the following entries:

nats: empty set
adx: {1}
zeros: empty set
cons: empty set
0: empty set
incr: {1}
s: empty set
hd: {1}
tl: {1}
The QTRS contained all rules created by the complete Giesl-Middeldorp transformation. Therefore, the inverse transformation is complete (and sound).
