[seqfan] A108668

[Sean A. Irvine]

Hi,

I have been trying to reproduce A108668 in the OEIS:

http://www.research.att.com/~njas/sequences/A108668

However, when I try to run the sequence as described I get:

0, 15, 35, 49, 51, 59, 90, 96, 210, 212, 242, 246, 248, 252,
283, 288, 297, ...

which differs by not including 71, 81, 84.

My string starts like this:

0(1)234(5)67(8)91(0)1(1)1(2)(1)3(1)(4)15(1)(6)(1)718(1)9(2)0(2)
1(2)2(2)32(4)(2)5(2)6(2)(7)282(9)(3)0(3)(1)(3)233(3)(4)35(3)6(3
)7(3)839(4)0(4)(1)(4)2(4)34(4)(4)54(6)(4)74(8)49(5)(0)51(5)2(5)
(3)(5)45(5)(5)6(5)75(8)59(6)0(6)(1)6(2)(6)3(6)465(6)6(6)(7)6(8)
697(0)(7)17(2)(7)(3)7(4)757(6)(7)778(7)9(8)(0)(8)18(2)(8)3(8)4(
8)58(6)(8)7(8)8(8)(9)90(9)(1)929(3)(9)4(9)(5)96(9)79(8)(9)910(0)

This would indicate that 71, 81, and 84 should not be in the
sequence.  However, I'm not 100% certain I have followed the
description as intended.

The sequence is obviously finite because it is clearly impossible
to have more than 10 digits in a row without erasure.  Hence,
the largest member is certainly less than 10^10.

Sean.
