Presentation

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

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

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

GAP

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

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