New lower bounds are obtained for the number $\mathscr N_{\mathrm B}(x)$ of Novák numbers not exceeding the given quantity $x$. In addition, conditioned on the generalized Riemann Hypothesis, upper bounds are found for the number of prime factors of Novák numbers and a description of the prime factors of Novák numbers $N$ such that $2N$ is a Novák-Carmichael number is presented. Bibliography: 7 titles.
Keywords: Novák numbers, large sieve.
