Presentation

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

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

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

GAP

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

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