Presentation

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

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

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

GAP

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

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