Presentation

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

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

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

GAP

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

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