Oddly CANs are defined similarly, except only odd primes are allowed in the factorization. It is conjectured that the ratio of consecutive oddly CANs is always a prime number. The sequence of those prime numbers is given in A110465. %H A110464 Amiram Eldar, <a href="/A110464/b110464.txt">Table of n, a(n) for n = 1..65</a> (calculated from A110465) %H A110464 Lawrence C.
