Presentation

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

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

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

GAP

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

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