Presentation

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

A minimal faithful permutation representation — 7 generators on 22 points:

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

GAP

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

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