The paper conjectures the exact form of the four-loop anomalous dimension of
a Konishi operator including contributions from the so-called wrapping
interactions. Two recent quantum field theory computations of the same
quantity contradict the conjecture (but do not agree on the precise form of
the result). We will discuss the basis of the conjecture.
