Presentation

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

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

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

GAP

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

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