Hello SeqFan,

Jim Nastos having found a wrong digit somewhere here :

   > 12,14,15,18,24,26,36,64,76,91,92,162,601,791,801,861,862,991,1091,1109...
   >
   > a) a(n) says « Consider the sequence as a succession of *digits* ; then,
   >    in position a(n), there is a "6" digit »
   > b) read all a(n)s backwards: those are the positions of all "9" digits
   >    in the sequence...

... I've decided to change a few integers & to integrate 69, of course ;-)

12,13,15,17,24,36,64,67,69,81,93,162,172,179,182,263,291,293,309,312,391,
401,402,403,496,506,561,901,1091,1106,1107,1108,1206,1291,1301,1391,1409...

Notice that palindromic integers are forbidden here, so as integers ending
in "0".

Love,
É.
