Feb 24 at 17:00 comment added Henri Cohen As the OP clearly noticed, his formula is equivalent to the identity $$\sum_{n\ge1}H_n^{(2)}/((n+1)(2n+1)\binom{2n}{n})=\pi^4/972$$ which is probably known and easier to prove.
Feb 24 at 15:23 comment added Martin.s I'm not sure because the integral came up in my discussion group, and the result matches numerically.
Feb 24 at 15:04 comment added GH from MO Why do you think your integral equals $\pi^4/1944$?
Feb 24 at 13:58 comment added Martin.s @GHfromMO sorry sir, I'm a new user on MathOverflow, and I edited the question, but I'm not sure if it was a good edit.
