Presentation

minimal degreeμ(G) = 22
transitive degreeμt(G) = 128

A minimal faithful permutation representation — 6 generators on 22 points:

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