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