That is 1/F1 where F1 is the first Feigenbaum constant a/k/a delta.
The mathworld article is pretty good:

  http://mathworld.wolfram.com/FeigenbaumConstant.html

It mentions that both constants were calculated to about 1000 digits in
1999.  I don't know how that was done, but presumably they could be
calculated to more digits these days if someone felt like it.
