Question 3

There are $2006$ points in space, no four of which are coplanar. Join every pair of points by a segment. A natural number $m$ is called good if each segment can be assigned a natural number not exceeding $m$ so that every triangle formed by any three of the points has two sides assigned equal numbers and its remaining side assigned a number greater than those two numbers. Find the smallest good number.
