Editing Heptadecagon (section)

===Heptadecagrams===
A heptadecagram is a 17-sided [[star polygon]]. There are seven regular forms given by [[Schläfli symbol]]s: {17/2}, {17/3}, {17/4}, {17/5}, {17/6}, {17/7}, and {17/8}. Since 17 is a prime number, all of these are regular stars and not compound figures.
