Presentation

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

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

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

GAP

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

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