Presentation

minimal degree	μ(G) = 22
transitive degree	μ_t(G) = 128

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

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

GAP

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

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