n-uniform tilings

[Brian L. Galebach]

Thank you very much for looking that up for me!  I guess my memory is just a
bit fuzzy for going 10 years back.  Anyway, I really appreciate you taking
the time to look that up.

Sincerely,
Brian Galebach

Exercise *6 on p.70 is `Determine all the 3-uniform
tilings.

It says that

D. P. Chavey, Periodic tilings and tilings by
regular polygons, PhD thesis, Univ of Wisconsin,
Madison, 1984

determined that there are 61 tilings of this kind.
