Presentation

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

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

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

GAP

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

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