Presentation

minimal degreeμ(G) = 22
transitive degreeμt(G) = 256

A minimal faithful permutation representation — 5 generators on 22 points:

(7,8)(9,10)(11,12)(13,14)(16,18)(20,22);(7,8)(9,10)(15,16,17,18)(19,20)(21,22);(1,2);(4,6)(8,10)(11,12,13,14)(15,16)(17,18);(3,4)(5,6)(7,8)(9,10)(11,12)(13,14)
