The omega constant is defined as
|
(1)
|
(OEIS A030178), where is the Lambert W-function.
It is available in the Wolfram Language
using the function ProductLog[1].
can be considered a sort of "golden ratio" for exponentials since
|
(2)
|
giving
|
(3)
|
The omega constant is also given by the power tower
|
(4)

where .
A beautiful integral involving given by
is due to V. Adamchik (OEIS A115287; Moll
2006; typo corrected).
