Hi Eric, 

I did have an old basic program that produced this sequence  to 

thousands of terms. 

I will see if I can find it.

Subject: [seqfan] Skolem with digits 

Hello SeqFans, 
This is a Skolem-like sequence S where all natural integer appear exactly twice and where two equal terms T of S are separated by exactly T < digits >. 


The above 3-digit terms aaa, bbb, ccc,... are missing (I am unable 
to compute them by hand). Could someone find them and extend S? 
S should be, of course, the lexicofirst such sequence. 
S could be seen as the "digit-version" of http://oeis.org/A026272
