| The geometry of the house is based on that of an elliptical toroid. |
| Here we examine this in detail, first looking at the case of a circular toroid deformed into an ellipse. |
| We then look at the case of a toroid compressed in the plane of the toroid. |
| It is an asymmetrical oval slice of toroid, tilted out of the ground towards the south to catch the sun's heat. |
| By contrast, the central region of Macrobdella Hb contains a hexagonal toroid at a resolution of 4 nm. |
| The structural role of the toroid was assumed to be a pier to which two bracelets are fixed by 12 connections. |
