(1 point) Consider the points which satisfy the equation y2x3+ax+bmodp where a=6,b=3, and p=19. This curve contains the point P=(2,2). Enter a comma separated list of points (x,y) consisting of all multiples of P in the elliptic curve group with parameters a=6,b=3, and p=19. (Do not try to enter O, the point at infinity, even though it is a multiple of P.) What is the cardinality of the subgroup generated by P
