Theorem
The following formula holds: $$\displaystyle\int_{\infty}^{\infty} F_m(it)F_n(it) \mathrm{sech}^2\left(\dfrac{\pi t}{2} \right)\mathrm{d}t = \dfrac{4(1)^n}{\pi (2n+1)} \delta_{mn},$$ where $F_n$ denotes the Bateman F, $i$ denotes the imaginary number, $\mathrm{sech}$ denotes sech, $\pi$ denotes pi, and $\delta$ denotes Kronecker delta.
