# Tunnels

Mice had built an underground house consisting of chambers and tunnels:

• each tunnel leading from the chamber to the chamber (none is blind)

• from each chamber lead just three tunnels into three distinct chambers,

• from each chamber mice can get to any other chamber,

• in the house is just one tunnel such that the it burying house divided into two separate parts.

How many chambers could at least have a mouse house? Sketch how chambers can be interconnected....
