Presentation

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

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

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