Presentation

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

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

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

GAP

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

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