SUMMARY
The series $$\frac{1}{4!}+\frac{4!}{8!}+\frac{8!}{12!}+\frac{12!}{16!}+\cdots$$ converges to the exact value of $$\frac{\ln 64 - \pi}{4!}$$, which approximates to 0.0423871. The transformation of the series involves the use of binomial coefficients and integrals, specifically the formula $$\frac{1}{\binom{n}{k}} = k\ \int_{0}^{1} (1-x)^{k-1}\ x^{n-k}\ dx$$. The final evaluation of the series is derived from the integral $$4\ \int_{0}^{1} \frac{(1-x)^{3}}{1-x^{4}}\ dx$$, leading to the logarithmic and pi components in the result.
