Presentation

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

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

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