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

GAP

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

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