Presentation

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

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

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

GAP

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

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