Okay, different bases. If the base is prime p, high value is clearly p; any value 1..p-1 will take that long to give a "0", and will generate all other digits before then. For base 4, I get 6 (3x2) from initial value 2=(4/2). For base 6, I get 20 (5x4) from initial value 13_6=(36/4) (_6 means written in base 6). For base 8, I get 28 (7x4) from 2 (8/2) For base 9, I get 24 (8x3) from 3 (9/3). For base 10, I get 72 (9x8) from 125 (1000/8). For base 12, I get 99 (11x9) from 14_12 (144/9). -tom On Thu, Dec 15, 2011 at 2:51 PM, Allan Wechsler <acwacw@gmail.com> wrote:
Thank you. By the way, the smallest x with a(x) = 4 is 266. The smallest x with a(x) = 3 is 1692. And a(13485) is the first occurrence of 2. (13485; 26970. Neat.)
I didn't search exhaustively, but it seems obvious that a(1023456789) is the first 1.
