Burdett DNA Project using 12 markers and creating nodes to connect nodes of genetic distance 3.

By stretching "relationship" to a ridiculous level, this finds distant connections between groups 1a, 1b, 1c, 3, and kits 73710 and 74551. Most of the connections are through 39805, which is 3 away from 74551, 3 away from two widely separated members of group 3, and 2 away from 73710, and 1 away from all the members of groups 1a and 1b.
