Presentation

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

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

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

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

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