It is shown that, for any k, there exist infinitely many positive integers n such that in the prime power factorization of n!, all first k primes appear to even exponents.

β¦ Synopsis
In 1997 Berend proved a conjecture of Erdo s and Graham by showing that for every positive integer r there are infinitely many positive integers n with the property that
where p(1)=2, p(2)=3, p(3)=5, ... is the sequence of primes in ascending order, and e p (m) denotes the order of the prime p in the prime factorization of the positive integer m. This article presents conjectures and results for the more complicated situation where an arbitrary pattern of residues modulo 2 is given.

The parity of exponents in the prime power factorization of n! is considered. We extend and generalize Berend's result in [On the parity of exponents in the factorization of n!,
An RSA modulus is a product M ΒΌ pl of two primes p and l. We show that for almost all RSA moduli M, the number of sparse exponents e (which allow for fast RSA encryption) with the property that gcdΓ°e; jΓ°MΓΓ ΒΌ 1 (hence RSA decryption can also be performed) is very close to the expected value.
## Abstract A __covering__ is a graph map Ο: __G__ β __H__ that is an isomorphism when restricted to the star of any vertex of __G__. If __H__ is connected then |Ο^β1^(__v__)| is constant. This constant is called the __fold number__. In this paper we prove that if __G__ is a planar graph that cover
