“…We first recall C(n, m 1 , m 2 , • • • , m r ) is a undirected graph consisting of r cycles sharing a common path of length n. In this section, we compute the determinant of the distance matrix for a class of C(n, m 1 , m 2 , • • • , m r ). In literature, similar problems has been studied for the cases r = 1, 2 (for details see [3,8,9,10,15]) and we have shown that some of their results can be extended for r ≥ 3. We recall some results for the case r = 1, i.e.…”
