Presentation

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

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

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

GAP

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

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