The Turan number of a graph H, denoted by ex(n, H), is the maximum number of edges in an n-vertex graph that does not have H as a subgraph. Let TPk be the triangular pyramid of k-layers. In this paper, we determine that ex(n, TP3) = 1/4n(2) + n + o(n) and pose a conjecture for ex(n, TP4). (C) 2022 Published by Elsevier B.V.
