# Leo group operations. ## Run Guide To run this program, run: ```bash leo run main ``` ## Execute Guide To execute this program, run: ```bash leo execute main ``` ## Overview This example shows how to do basic operations over groups. It takes the input data from inputs/groups.in ## Documentation Group Element The set of affine points on the elliptic curve passed into the Leo compiler forms a group. A subset of those points, defined by a chosen generator point, forms a subgroup of the group. Leo supports the set of points in this subgroup as a primitive data type. Group elements are special since their values can be defined as coordinate pairs ```(x, y)group```. The `group` type keyword group must be used when specifying a pair of group coordinates since implicit syntax would collide with normal tuple `(a, b)` values. ``` let a = 0group; // the zero of the group let b = group::GEN; // the group generator let c = (0, 1)group; // coordinate notation ```
