Dear Mr. Conway,
I was wondering if you could assist me in my persuit for
knowledge. As odd as it may sound its actually quite essential to my
research that i know. I've searched the internet thoroughly and cant
seem to find exactly what im looking for. I have a series of questions
isnt possible or doesnt exist i would be more than willing to hear a
detailed explanation if your willing to produce one. What is the name
of a 61 sided figure in Latin, English and greek? Will the name of
this figure change if it consists of triangles, pentagons, hexagons,
..., or dodecagons? Finally, will the figure still have the same name
if the sides of the figure are concave?
If you could assist me in this matter i would be more grateful
than i believe that i can express in words. Thank you for your time
sir.

Sincerely,
-Laike-
