Kang–Kelly–Kühn–Methuku–Osthus random design existence conjecture
Let be the random -uniform hypergraph on vertices, and let an -Steiner system be a collection of -sets containing every -set exactly once. Kang–Kelly–Kühn–Methuku–Osthus conjecture. For every , if
for all and , then asymptotically almost surely contains an -Steiner system. This is the upper-bound formulation of the conjectured random threshold, and the source gives no resolution status.
