Presentation

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

A minimal faithful permutation representation — 7 generators on 22 points:

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

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

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