### Description

It has been conjectured that glueballs can be described by knot solitons in a low energy effective model of the Yang-Mills theory. In this talk, we consider knot solitons in the $F_2$ Skyrme-Faddeev-Niemi model, which can be interpreted as a low energy effective model of the $SU(3)$ Yang-Mills theory. It will be shown that the Euler-Lagrange equation reduces to that of the well-known $CP^1$ Skyrme-Faddeev-Niemi model. We also discuss some relation between the knot solitons and classical gauge vacua.
