     Moreover, if $l<k$ and the girth of $D$ is at least $l+1$, then these two numbers are equal. The number of semikernels of $D$ is equal to the number of semikernels of ${\mathcal {L}}D$. Also we introduce the concept of $(k,l)$-Grundy function as a generalization of the concept of Grundy function and we prove that the number of $(k,l)$-Grundy functions of $D$ is equal to the number of $(k,l)$-Grundy functions of any partial line digraph ${\mathcal {L}}D$..
