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

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