WeightGap {wgDimension = 1, wgDegree = 0, wgKind = Algebraic, wgUArgs = UArgs, wgOn = WgOnAny}
Proof:
The weightgap principle applies using the following nonconstant growth matrix-interpretation:
We apply a matrix interpretation of kind constructor based matrix interpretation:
The following argument positions are considered usable:
uargs(h#) = {1},
uargs(c_2) = {1}

TcT has computed the following interpretation:
p(a) = [0]

Following rules are strictly oriented:

Following rules are (at-least) weakly oriented:

= g(h(a()))
Further, it can be verified that all rules not oriented are covered by the weightgap condition.
