In this note we show a new upperbound for the function ex(n; TKp), i.e., th
e maximum number of edges of a graph of order n not containing a subgraph h
omeomorphic to the complete graph of order p. Further, for inverted right p
erpendicular 2n+5/3 inverted left perpendicular less than or equal to p < n
we provide exact values for this function.
