 OFFSET 1,1 COMMENTS By an interesting approach I was able to find a(7). [From Farideh Firoozbakht, Sep 30 2009] LINKS EXAMPLE Both numbers reversal(37)=73 & reversal(37^2)=9631 are primes and 37 is the smallest prime number with this property so a(2)=37. CROSSREFS Cf. A118212, A118213, A165696, A165698.
