Observing this sum
$$sum_{n=0}^{infty}frac{{2n choose n}^3}{64^n}f(n)$$ we got these two results:



$$sum_{n=0}^{infty}frac{{2n choose n}^3}{64^n}cdot frac{n}{(2n-1)^2}=frac{8pi}{Gamma^4left(frac{1}{4}right)}tag1$$



$$sum_{n=0}^{infty}frac{{2n choose n}^3}{64^n}cdot frac{1}{(2n-1)^3}=-frac{48pi}{Gamma^4left(frac{1}{4}right)}tag2$$



How can we prove them?
