[seqfan] Re: The most and least interesting sequences not in OEIS

[jean-paul allouche]

I agree with the fact that the true question about "is known" is
"is known by whom". For example about pi and the Bible, see

On the Rabbinical Approximation of π
Historia Mathematica, Volume 25, Issue 1, February 1998, Pages 75-84
Boaz Tsaban, David Garber
