  We consider the double scaling limit of a model of Pauli spin operators
recently studied in Hanada et al. [1] and evaluate the moments of the
Hamiltonian by the chord diagrams. We find that they coincide with those of the
double scaled SYK model, which makes it more likely that this model may play an
important role in the study of holography. We compare the model with another
previously studied model. We also speculate on the form of the Hamiltonian in
the double scaling limit.
