Properties of primes
TL;DR: In this paper, 60 open problems on combinatorial properties of primes are posed for further research. But the authors of this paper assume that π(x) and p n have the same properties as Riemann's Hypothesis.

Finite covers of groups by cosets or subgroups
TL;DR: In this paper, the authors considered combinatorial aspects of finite covers of groups by cosets or subgroups, and they showed that there is a composition series from the identity element of a group to all the subgroups of the group to a subgroup whose factors are of prime order.

Binomial Coefficients and Quadratic Fields
TL;DR: In this paper, a real quadratic field with discriminant d and p being an odd prime not dividing d was considered, and it was shown that the modulo p^2 in terms of Lucas numbers, the fundamental unit and the class number of E, where (d/c) is the Kronecker symbol.
