Presentation

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

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

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

GAP

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

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