amphicheiral

— My soul's an amphicheiral knot Upon a liquid vortex wrought By Intellect, in the Unseen residing. And thine dost like a convict sit With marlinspike untwisting it Only to find its knottiness abiding; Since all the tools for its untying In four dimensioned space are lying, Wherein thy fancy intersperses Long avenues of universes, While Klein and Clifford fill the void With one finite unbounded homaloid, And think the Infinite is now at last destroyed.
