We present a general description of the rich cluster of galaxies Abell 754, including a discussion of some aspects concerning its evolution, and present an analysis of the orientations of the galaxies in the cluster region. Previous studies from X-ray data and galaxy distributions have provided evidence for pronounced subclustering in this cluster. In this light, our aim has been to examine non-random effects in the galaxy orientations in rich clusters with particular regard to the presence of subclustering. Our results do provide evidence for non-random alignment of the galaxies in Abell 754 and confirm the presence of subclustering within this cluster. We intend to continue our investigations by studying, in a similar manner, other clusters the results for which will be published in due course.
