Presentation

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

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

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

GAP

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

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