  This paper focuses on the creation of a model with explicitly defined
symmetry-protected topological (SPT) phases on a triangular lattice as an
extension of $Z_2$ Ising model's ferromagnetic phase. Unlike in previously
known similar works, this model is based on an initially interacting system
which is known to describe experimentally realizable physical systems. The
Hamiltonian for these edge states contains four-point spin interactions between
next-to-next nearest neighbors. As an initially interacting A generic technique
for creating SPT models is developed, allowing for the construction of
translation-invariant edge models.
