Presentation

minimal degree	μ(G) = 22
transitive degree	μ_t(G) = 512

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

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

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

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