The second part is a review of the ``master'' model of HS particle which makes manifest the classical equivalence of two previously known HS particle formulations and gives rise to new massless HS multiplets.7 pages, talk given at the XXII Max Born Symposium ``Quantum, Super and Twistors'' in honor of the 70th birthday of Prof. Jerzy Lukierski, Wroclaw, September 2006High Energy Physics - TheoryNonlinear Realizations in Tensorial Superspaces and Higher Spinstext
