 ## Documentation Group Element
 
-The set of affine points on the elliptic curve passed into the Leo compiler forms a group. Leo supports this set 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.
