Presentation

minimal degreeμ(G) = 22
transitive degreeμt(G) = 128

A minimal faithful permutation representation — 7 generators on 22 points:

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

GAP

Past the SmallGroups library coverage — no SmallGroups id. Construct it from a minimal faithful permutation representation:
