Presentation

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

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

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

GAP

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

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