F,q,p  A finite field F of characteristic p and #F = q = p^m.  For prime fields, q = p; otherwise, q = p^m and m>1. 
E  Elliptic curve.  E is specified by an equation and a field F. 
n  Number of points on the elliptic curve E.  n = h * r, for h and r defined below. 
G  A primeorder subgroup of the points on E.  G is a destination group to which byte strings are encoded. 
r  Order of G.  r is a prime factor of n (usually, the largest such factor). 
h  Cofactor, h >= 1.  h is an integer satisfying n = h * r.
