We present a novel approach to the age-old question of whether perfectcuboids exist. Our approach consists of two new computer search algorithms,arising from the analysis of "perfect plinths" reported by one of us recently,that are much more efficient than any prior algorithm of which we are aware.Using this approach, we also (i) identify some new two-parameter families ofedge cuboids, and (ii) show that large proportions of aspect ratios of faces orinternal rectangles cannot be present in a perfect cuboid, a property that waspreviously reported only for faces with the aspect ratio 4:3.

Novel required properties of, and efficient algorithms to seek, perfect cuboids
