Query: N=2 supersymmetric extension of l-conformal Galilei algebra   N=2 supersymmetric extension of the l-conformal Galilei algebra is
constructed. A relation between its representations in flat spacetime and in
Newton-Hooke spacetime is discussed. An infinite-dimensional generalization of
the superalgebra is given.
