Grand Trine

The aspect pattern formed when three planets, each in a different sign of the same triplicity (air, earth, fire or water), trine each other. A grand trine permits smooth flow of energies among the planets involved in accordance with the triplicity occupied. A dissociate grand trine, one in which the three planets fall within orb to form mutual trines but do not occupy the same triplicity, supplements ease of planetary expression but lacks the cohesiveness of a grand trine formed between planets occupying one triplicity.

An alternate term for grand trine is trigon, the three member signs of a triplicity.
