Jul21 comment Combination with repetition problem This should be the approach that must be followed :) Jul16 comment How many squares can be formed from n equidistant points in a circle? so I guess my answer is correct for n=8?

Jul16 revised How many squares can be formed from n equidistant points in a circle? added 165 characters in body Jul16 comment How many squares can be formed from n equidistant points in a circle? yes, they are uniformly space along the circumference of the circle Jul16 comment How many squares can be formed from n equidistant points in a circle? sure lemme post a picture. Jul16 asked How many squares can be formed from n equidistant points in a circle? Jul16 accepted How do 3 points define a plane? Jul16 comment How do 3 points define a plane? Can you like give a non mathematical example to show why 4 points are a problem and 3 are not and for that matter is it a generalization that higher number of points pose problems to define a plane? Jul16 comment How do 3 points define a plane? The answer to the combinatorics question is like C(25,3) which I am not able to see why, can't 4 points define a plane? if yes then the answer should be C(25,3) + C(25,4) isn't it?
