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

GAP

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

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