Beyond the trivial case \PP^1 x \PP^1 we find 17 families which we explicitly describe. We reduce the problem to a combinatorial description of certain generating systems for finite groups which we solve using also MAGMA's library of groups of small order.40 pagesAlgebraic GeometryGroup Theory14J29, 14J10, 14E22, 14Q99, 20F05, 20F99text
