Acronym erich Name parallelly that elongated rich Confer uniform relative: rich   related CRF honeycombs: gyerich   6Q3-2S3-gyro   3Q3-S3-2P6-2P3-gyro

This CRF honeycomb is the elongated form of rich or likewise the ungyrated form of gyerich

Each etigybcu could be dissected into pairs of tricu and an equatorial hip. Then this honeycomb would become 3Q3-S3-2P6-2P3-gyro.
