This is a scaliform tetracomb, obtained as a variation of a faceting of the celliprismatotruncated icositetrachoric tetracomb (capticot, which likewise could be considered as celliprismatotruncated demitesseractic tetracomb). Or as a Stott addition of the snub icositetrachoric tetracomb (s3s4o3o3o, sadit) with the truncated hexadecachoral tetracomb (o3o4o3x3x, thext).
