Presentation

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

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

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