 Abstract
For any integer , each palindrome of n induces a circulant graph of order n. It is known that for each integer , there is a one-to-one correspondence between the set of (resp. aperiodic) palindromes of n and the set of (resp. connected) circulant graphs of order n (cf. [2]). This bijection gives a one-to-one correspondence of the palindromes with $gcd({\sigma})
