摘要：

We show that the m=12 superconformal theory (c= 10 7) with the (E6, D8) modular invariant exhibits a bigger symmetry algebra. It is argued that this is a super W3-algebra, and that this latter can be realized (after a projection)from the coset su(3)1{squared plus} su(3)3/su(3)4. We also argue that one has some chance to realize general super W-algebras from cosets g ̂k{squared plus} g ̂l/ g ̂k+l with l=hc, the dual Coxeter number of the (simply laced) Lie algebra g. © 1990.
