Presentation

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

A minimal faithful permutation representation — 7 generators on 22 points:

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

GAP

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

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