Gauss' constant should not be confused with the Gaussian gravitational constant. ==Relations to other constants== Gauss' constant may be used to express the Gamma function at argument 1/4: : Alternatively, : and since π and Γ(1/4) are algebraically independent with Γ(1/4) irrational, Gauss' constant is transcendental.
