Presentation

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

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

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