THE TAHTA 4D DIARIES

The list of factors in Euclidean 4-Place having exactly the same distance R from a fixed issue P0 varieties a hypersurface generally known as a 3-sphere. The hyper-quantity in the enclosed Place is: [11] even so the geometry of spacetime, currently being non-Euclidean, is profoundly various from that explored by Schläfli and popularised by Hinton
