[seqfan] Re: is continued fraction expansion of 2^(1/3) bounded?

[israel at math.ubc.ca]

The 19 terms currently present in A181495 require computing at least 
12918396 terms of the continued fraction of 2^(1/3). I don't know how many 
more were computed without finding another term, but the given Mma code 
computes 20000000. I think that's numerically very demanding, requiring 
terrifically high precision. Maybe somebody can grind out a few more terms, 
but I doubt we'll get enough to require a b-file.

Cheers,
Robert
