Abstract
The answer to the question in the title is contained in the following conjecture by So [Discrete Math. 306 (2006), 153–158]: There are exactly 2τ(n)−1 non-isospectral integral circulant graphs of order n, whereτ(n) is the number of divisors of n. In this paper we review some background about this conjecture, which is still open. Moreover, we affirm this conjecture for some special cases of n, namely,n = pk,pqk,p2q with primes 2 ≤ p
