Abstract<br />
This research presents an intuitive and straight forward method of capturing both structural redundancy and the<br />
multiplicity of social ties in a small network of 20 corporate directors across four different social spheres in 1962.<br />
Structural redundancy is best thought of as the opposite of a unique tie which emerges in a network of interlocking<br />
corporate directors once the affiliations from other non-corporate organizations are included. Unlike the analysis of<br />
structural redundancy, the multiplicity of ties recognizes that the number and the configuration of ties between a<br />
given pair of directors are both meaningful. By utilizing these concepts, the paper shows how social club ties in<br />
1962 were especially important in adding unique (i.e., non-redundant) ties among the corporate directors. The<br />
analysis of multiplicity reveals that over 60 percent of the directors had multiple ties and that 56 percent of the<br />
directors possessed ties stemming from two or more different types of social affiliations. These results underscore<br />
that there is more to the social cohesion among corporate directors than interlocks alone.<br />
