Dear Forum Members,

computations in permutation groups. Given G=<S> \le S_n,
generators for the point stabilizers (called a strong generating set)
can indeed be computed in polynomial time in |S| and n. The first
algorithm was given in

C. Sims: Computation with permutation groups, Proc. Second Symp. on
Symbolic and Algebraic Manipulation, ACM Press, 1971, pp. 23--28.

The first analysis that a version of Sims's algorithm runs in polynomial
time appeared in

M. Furst, J. Hopcroft, E. Luks: Polynomial-time algorithms for
permutation groups, Proc. 21st IEEE Symp. on Foundations of Computer
Science, IEEE Press, 1980, pp. 36--41.

The current asymptotically fastest strong generating set construction
is in

```L. Babai, E. Luks, \'A. Seress: Fast management of permutation groups I,
SIAM J. Computing 26 (1997), 1310--1342.
