Talk:Hyperbolic Geometry Exercises
Did some work that involved renumbering (Steve, I changed your course page to reflect the new numbers). Here's the changes:
- Old 7, new 16a.
- Old 8-12, new 7-11 (one lower).
- New problem 12.
- Old 16, new 16a and 16b.
All other numbers stay the same. Bryan 02:17, 15 April 2008 (CDT)
Here's a reference for #19 about how many 1-away, 2-away, 3-away vertices there are: A. Paul, N. Pippenger, A Census of Vertices by Generations in Regular Tessellations of the Plane, 2010. http://arxiv.org/abs/1006.4356 Bryan 22:32, 2 January 2011 (CST)
