Presentation

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

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

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

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

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