Presentation

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

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

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

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

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