We describe the compressed zero-divisor graphs of a commutative finite local rings $R$ of characteristic $p$ with Jacobson radical $J$ such that $J^4=(0)$, $F=R/J\cong GF(p^r)$ and ${\dim_F J/J^2=2}$, ${\dim_F J^2/J^3=2}$, ${\dim_F J^3=1}$ or ${\dim_F J/J^2=3}$, ${\dim_F J^2/J^3=1}$, ${\dim_F J^3=1}$.
Ключевые слова:finite ring, local ring, zero-divisor graph.
