[,12,], as an intermediate step. A recipe to go from Sims' generators to standard generators is given by Jansen and Wilson [6], and we use some results from [2] to find generators for the ,centralizer, as words in the standard generators. To do this, we do some calculations inside the permutation group G of degree 9606 125, 235 . 236 13 ...
