34	Calculate $\int_{0}^{1} (x-f(x))^{2016} dx$, given $f(f(x))=x$.
32	Are there infinitely many primes $p$ such that $p-2$ and $p+2$ are composite?
24	The square roots of different primes are linearly independent over the field of rationals
22	Elementary solution of exponential Diophantine equation $2^x - 3^y = 7$.
16	Why does “solvability” for groups suggest something about the solution of polynomials?
