Presentation

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

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

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

GAP

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

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