Succeeding paper[1]

here we discuss the problem of enumeration on the classes of Adam isomor phism of circulant digraph. In this paper

we obtained the formulae of enumeration of the following iso morphic classes of circulant digraphs: ⅰ) ■(n

2)={C(n

a1

a_@)|a1

a2≠0 and (a1

a2

n)=1}. ⅱ) ■(n

3)={C(n

a1

a2

a3

)|a+1≠0 and(a1

a2

a3

n)=1

n=pa

p is prime and p≠2}. ⅲ) ■(n

4)={C(n

a1

a2

a2

a4)|a1≠0 and(a1

a2

a3

a4

n)=1

n=pa

p is prime and p≠2}.
