Presentation

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

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

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

GAP

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

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