Presentation

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

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

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

GAP

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

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