**2013** - Counterexamples for Frobenius primality test,
arxiv.org/abs/1307.7920.

At present one can not find a single counterexample to even a simplest version of Frobenius primality test. The assessment of probability of the mistake, presented in [I.B. Damgard and G.S.Frandsen, Journal of Cryptology, 2006] is strongly overestimated. In the present paper, the properties of simple divisors of FPP-numbers are proved. The lower bound for FPP are given. - List of some known Runge-Kutta methods family (Maple, source code)
