Kelly's conjecture on reconstructibility from vertex-deleted decks

About 10 years old · traced to

Let l∈Nl\in\mathbb{N}. An ll-card of a graph is an induced subgraph obtained by deleting ll vertices, and the corresponding deck is the multiset of all such cards. A graph is ll-reconstructible if it is determined by this deck.

Kelly's conjecture. For l∈Nl\in\mathbb{N}, there is an integer MlM_l such that any graph with at least MlM_l vertices is reconstructible from its deck of cards obtained by deleting ll vertices.

This is a more detailed version of the Reconstruction Conjecture. The original conjecture is the special case M1=3M_1=3; the asserted existence of a threshold for every ll remains open.
