Presentation

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

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

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

GAP

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

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