摘要
By ''3-graph'' we mean a pair (V, E) such that E subset of or equal to [V](3). We show that the only non-trivial finite 3-graphs homogeneous in the sense of Fraisse are those associated with the projective planes over GF(2) and GF(3), and with the projective lines over GF(5) and GF(9). To exclude other possibilities we use the classification of doubly transitive finite permutation groups.
