This paper studies the broadcast function B(n). We consider the possible vertex degrees and possible connections between vertices of different degrees in graphs with \(b(G) = {\left\lceil\log_2 n\right\rceil}\). Using this, we present improved lower bounds on B(n) when n = 2 k  − 2 p and n = 2 k  − 2 p  + 1 (3 ≤ p < k). Also, we prove that B(24) ≥ 36 for graphs with maximum vertex degree at most 4.
