Presentation

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

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

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