Conversely is not true. For example, a(10)=59 appears only once, although 10 is not prime. %H A182482 Ray Chandler, <a href="/A182482/b182482.txt">Table of n, a(n) for n = 1..10000</a> %e A182482 All places where 71 appears are 4,6,12. "Thus" 12 is multiple of 4 and 6. %e A182482 Since (101+1)/6=17 is prime, then 101 appears only once. %Y A182482 Cf.
