Presentation

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

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

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

GAP

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

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