Hexabolo Models Constructed with Pentaboloes
The 30 pentaboloes cover an area of 30*5/2=75 s-square units.
A hexabolo model five times as wide needs 6/2*5*5=75
s-square units. Therefore the models must be constructed with all
Since the shapes are rather irregular, the sequences for the places
to cover must be carefully chosen to get fast solutions.
If there are only s-edges the problem is hard to solve as mentioned for
the 15x5 s-rectangle .
