The deck of a graph (Formula presented.) is given by the multiset of (unlabeled) subgraphs (Formula presented.). The subgraphs (Formula presented.) are referred to as the cards of (Formula presented.). Brown and Fenner recently showed that, for (Formula presented.), the number of edges of a graph (Formula presented.) can be computed from any deck missing 2 cards. We show that, for sufficiently large (Formula presented.), the number of edges can be computed from any deck missing at most (Formula presented.) cards.@en
