help needed with a duplicate

Yes, it is indeed possible that n occurs more than once as a substring of 
2^n in decimal. I could have been better written

%N A124692 A000000(n) first occurs as a substring of 2^A000000(n) starting 
at the a(n)th digit from the left.
%S A124692 
1,1,3,10,2,10,5,3,11,13,2,5,20,4,3,24,19,5,17,19,35,25,53,67,60,61,33,74,18,109,

(and would have if I were interested in correcting this particular 
sequence). This retitling makes the sequence correct, if not as thorough as 
some might like.

This criticism totally misses the point of my post: In general, indexing a 
sequence on the proper domain is preferable to using arbitrary values to 
indicate undefined elements.

Seqfans, it looks like you cannot submit a new sequence 
- or a prenumbered new sequence - you don't get
the usual acknowledgement, and the sequence never reaches me

"Comments" don't reach me either

It looks like this started 2 or 3 days ago

This is only on the machine
outside the firewall - things work OK when I test them myself

you should assume that all new sequences and comments
for the past few days may have been lost
