Presentation

minimal degree	μ(G) = 22
transitive degree	μ_t(G) = 256

A minimal faithful permutation representation — 6 generators on 22 points:

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

GAP

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

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