It is proved that if a planar triangulation different from K3 and K4 contains a Hamiltonian cycle, then it contains at least four of them. Together with the result of Hakimi, Schmeichel, and Thomassen [21, this yields that, for n 2 12, the minimum number of Hamiltonian cycles in a Hamiltonian planar

The interval number of a simple undirected graph G, denoted i(G), is the least nonnegative integer r for which we can assign to each vertex in G a collection of at most r intervals on the real line such that two distinct vertices u and w of G are adjacent if and only if some interval for u intersect
Let T 2 n be the set of all triangulations of the square [0, n] 2 with all the vertices belonging to Z 2 . We show that Cn 2 <log Card T 2 n <Dn 2 . ## 1999 Academic Press Triangulations with integral vertices appear in the algebraic geometry. They are used in Viro's method of construction of real
Given an orientable or nonorientable closed surface S and an integer n not less than 3 and not greater than the chromatic number of S, we construct a graph admitting a triangular embedding in S and having chromatic number n. In general we follow the terminology and notation of [3].
