Abstract

In this paper, the fine triangle intersection problem for a pair of maximum kite packings is investigated. Let Fin(v) = {(s, t): a pair of maximum kite packings of order v intersecting in s blocks and s + t triangles}. Let Adm(v) = {(s, t): s + tb v , s, t are non-negative integers}, where b v = └v (v −1)/8┘. It is established that Fin(v) = Adm(v)\{(b v − 1, 0), (b v − 1, 1)} for any integer v ≡ 0,1 (mod 8) and v ≥ 8; Fin(v) = Adm(v) for any integer v ≡ 2, 3, 4, 5, 6,7 (mod 8) and v ≥ 4.
