摘要：  In the talk, a counterexample to some Khukhro-Borovik's conjecture on locally finite groups with bounded c-dimension will be constructed. This construction is closely connected with a well-known open Peter Neumann's conjecture: there are infinitely many primes p such that |PSL(2,p)| is a product of exactly six primes. Our construction is based on a weak variant of Neumann's conjecture that was proved by K.Aladi, R.Solomon, and A.Turull and that is an analog of Jingrun Chen's theorem for the twin primes problem.
