Name  hyperbolic order 7 heptagram tiling 
Circumradius  sqrt[(1cos^{2}(π/7))/(12 cos(π/7))] = 0.484510 i 
Vertex figure  [(7/2)^{7}] 
Dual  o7/2o7x 
Confer 

This hyperbolic star tiling can be obtained as a stellation of o3o7x. Every part of the tiling will be covered twice: by the convex central part and by the pointy ones.
