The disambiguation page exists only to provide alternate (and obscure) dictionary definitions for quaternion. Looking through the page history, one finds that it also used to contain a redlink to an obscure musical composition [1]. Four years later, the redlink still has not been created. That leaves its only content as dictionary definitions. WP:NOTDICDEF, so it should be deleted. Ozob (talk) 09:28, 3 January 2009 (UTC)[reply]
Not only has Kusma found another meaning of quaternion, but it turns out that the redlink I mentioned above is mentioned on list of quarter tone pieces. Since there's at least three things to disambiguate, my former reasoning no longer stands. I withdraw the nomination. Ozob (talk) 20:29, 3 January 2009 (UTC)[reply]
