Killing my boredom, I played a bit on Geogebra and started this uniform hyperbolic pattern consisting of 8 circles per vertex.
Considering my Poincaré disk model is of Gaussian curvature -1, and using if possible the circumference of a circle of radius $r$ being equal to $2\pi\sinh(r)$, what is the radius of the circles?
Bonus points if you can name this pattern.
