So 8 corners of the cube, 8 triangular openings of the Octahedron, ergo the 8 triangular openings of the Vector Equlliibrium/cubo-octahedron.

.."The data showed that the first divisions after fertilization were not regulated across mice, rabbits, and monkeys. The cells divided randomly until they reached the 8-cell stage, a stage where all embryos suddenly started to look the same. "After looking very different in the first stages, embryos seemed to converge toward each other's shape at the end of the 8-cell stage," Hannezo continues. But how come? What brings structure to this chaos?
An embryonal Rubik's cube -- cell cluster optimizes its packing
Corominas-Murtra and Hannezo, both theoretical physicists, were fascinated by this dataset and set out to understand this process from a theoretical standpoint.
However, an embryo's shape is highly complex, making it difficult to determine what it means for two embryos to be similar or different. The scientists discovered that they could effectively approximate the full complexity of the structure of an embryo simply by studying the configurations of the cell-to-cell contacts. "We think that we can derive most of the important details about the morphology of an embryo by understanding the arrangements of cells or knowing which cells are physically connected -- similar to connections in a social network."...
