Conjecture that the exact induced density formula holds for all graph sizes

About 8 years old · traced to

Let HH be a strongly asymmetric graph on hh vertices. Let iH(n)i_H(n) be the maximum number of induced copies of HH in an nn-vertex graph, and let g(n,h)g(n,h) be the recursively defined nested-blowup count. Exact density conjecture. For every n∈Nn\in\mathbb{N},

iH(n)=g(n,h).i_H(n)=g(n,h).

Consequently, the inducibility of HH satisfies

iH=h!hh−h.i_H=\frac{h!}{h^h-h}.

The preceding theorem establishes the formula only in the range covered there; this conjecture proposes its extension to all nn for strongly asymmetric graphs.
