In the paper it was argued that the top-quark mass arises from the alignment of left-handed isospin vectors S = (1 5) of neighboring tetrahedrons with a Hamiltonian given by Eq. (43) of the paper. It was further argued that the b- quark mass arises from a small admixture to S of right-handed isospin vectors T = (1 + 5) (see Eq. (45) of the paper). The latter statement is wrong. Instead, the presence of 2 Higgs doublets inherent in Eq. (21) is equivalent to the alignment both of left-handed vectors Si and of right-handed vectors T i between 2 tetrahedrons. Indeed, the alignment of the Si corresponds to a VEV for the U-tetron, and the alignment of the T i corresponds to a VEV for the D-tetron. (Formula Presented).
