# How many 4 dimensional "solids" are there? (Inspired by Tim Y. 's question)

There are five platonic solids for the 3 dimensional figures.[en.wikipedia.org/wiki/Platonic_solid][ I wonder which kinds of 3 dimensional figures will make up the 4 dimensional figure... https://en.wikipedia.org/wiki/Tesseract There must be a sphere within a sphere...

There are 6 regular, convex "solids", or polytopes, in 4 dimensions. http://en.wikipedia.org/wiki/Convexregular4-polytope
