I think I might have found some info into the shape of this if anybody is interested.
[FONT=Georgia,Garamond,Palatino,Times New Roman,Times,serif]* Grand aspects. These are very rare in occurrence, but they can crop up, often inaccurately but all the same powerful during their period of operation. The grand trine and grand cross are the most common, but it is also possible to meet up with a grand sextile, grand octile, or a grand minor aspect form at occasional points in history. Try counting how many individual aspects are at work in a grand sextile! At these points in time, a very strong resonance is set up which, in the character of the individual planets concerned, can make for a power point of supreme proportions. A very special message comes forward at such a time. Many oppositions are involved, creating an intense and sharp atmosphere, but the peripheral aspects will show how the energy is released by all-round integration of all of the energies present in the configuration, an alchemic fusion. A grand sextile can make so much happen, so much energy to flow, that it can become cathartic. A grand octile can set up such a thoroughly challenging dilemma that potential for resolution is infinitely expanded, through sheer pressure: otherwise everything must stop, and entropy sets in. Grand aspects are very powerful!
