Talk:Heptagon

message: Look at Talk:Hexagon and Talk:Diagonal. We know the figure for a hexagon is 25, but does anyone know the figure for the heptagon?? In addition, can anyone find a pattern?? Please put the formula in at Talk:Diagonal if you know a formula. 66.32.241.33 00:05, 13 Jun 2004 (UTC)

message: Is it possible to use a Heptagon in combination with another regular polygon to tile the plane?   
If it is not, what if one of its sides were replaced with a concave or convex curve, and another regular polygon had one of its sides replaced with an opposite curve?   216.99.201.74 (talk) 03:05, 22 June 2009 (UTC)

message: can you please explain the first diagram. exactly how is point "A" found in order to make angle "PAO". what determines the length of the unamed line segment point a is on. 71.232.147.54 (talk) 00:26, 10 April 2011 (UTC)
thread_title:  construction 

message: The article used to claim that "Apart from the heptagonal prism and heptagonal antiprism, no polyhedron made entirely out of regular polygons contains a heptagon as a face". Interestingly, this isn't true! I changed "polyhedron" to "convex polyhedron" to account for these non-convex polyhedra.  — Preceding unsigned comment added by 69.193.216.26 (talk) 21:35, 26 April 2013 (UTC)

message: The left image is very good and easily comprehensible and therefore needs no special description.
The right image (method of John Horton Conway) for me is still a mystery! 
Who can show me how will the neusis construction achieved? 
Where and how is the construction tool "neusis" used? 
Who knows a reference to this construction? 
Thanks in advance for your efforts! Greetings Petrus3743 (talk) 09:29, 22 November 2015 (UTC)

message: To an Administrator,
please check the endorsement "This article includes a list of references, but its sources remain unclear because it has insufficient inline citations. ...." Is it still required? Thank you for your efforts! Greetings Petrus3743 (talk) 13:07, 4 December 2015 (UTC)

message: Conway's notation has been replaced by Schoenflies notation for point groups. Salthouse and Ware give character tables for the subgroups D7, C7, C2v and Cs. The existence of 4 subgroups  appear to be inconsistent with the diagram. Petergans (talk) 15:07, 2 February 2018 (UTC)
thread_title:  Conway's notation 

message: The claim "There are also concave heptagon tilings possible in the Euclidean plane." cites the Polytope Wiki, a user generated wiki. This citation should be removed and if no reliable source for the claim can be found the claim should be removed. I would do it myself but I have a conflict of interest, so I'll let other editors make the actual edit if they agree my assessment. AquitaneHungerForce (talk) 22:51, 7 May 2024 (UTC)
