Presentation

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

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

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