Presentation

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

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

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

GAP

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

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