Presentation

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

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

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

GAP

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

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