Abstract: Let $ {k_0}$ be the least odd value of k such that $ k \cdot {2^n} + 1$ is composite for all $ n \geqslant 1$. In this note, we present the results of some extensive computations which restrict the value of $ {k_0}$ to one of 119 numbers between 3061 and 78557 inclusive. Some new large primes are also given.
