COMMENT

Also the decimal expansion of a solution to 1/(x^(1/(x+1))-1)-x.
The other solution is 1. Is the first 4 digits 3,1,4,1 a just a coincidence?
Perhaps Pi - 3.1410415254107... = 0.0005511281790... has a generating function.
Some experimentation will show that the recurrence
x = 1/(x^(1/(x+1))-1-1/x^8.446) converges to 3.14159264313...
Apparently related to A100086. [From R. J. Mathar (mathar(AT)strw.leidenuniv.nl), Sep 17 2008]
