[seqfan] Re: Sequence needing more terms, A6156, squarefree ternary words

[Hans Havermann]

I've collated terms 0-110 here:

http://chesswanks.com/seq/b006156.txt

Terms 1-90 come from the The Entropy of Square-Free Words by Baake,  
Elser, & Grimm (pages 10, 11). Terms 91-110 come from Grimm's Improved  
Bounds on the Number of Ternary Square-Free Words (page 3).
