[seqfan] Re: Sum of squares -- and a concatenation

[Eric Angelini]

Hello SeqFans,
Hans Havermann has checked and extended S (many thanks to him).
He wrote to me in a private mail that S is difficult to compute 
and extend.
Would someone else have a try (and check Hans' terms)?
And perhaps look for the seq T, which starts with a(1)=3,
for the seq U with a(1)=4, etc.?
Best,
É.
