 OFFSET 1,2 COMMENTS As it appears that the Sum {n>=1} (-1)^(n+1)/n^2 / Sum {n>=1} ((-1)^(n+1))/n^1 is the inverse of Levy's constant, or more traditionally the log of Levy's constant (A100199), this sequence which is equal to Sum {n>=1} (-1)^(n+1)/n^3 / Sum {n>=1} ((-1)^(n+1))/n^1 may be the inverse of the log of another constant with similar properties.
