Presentation

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

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

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