Presentation

minimal degree	μ(G) = 22
transitive degree	μ_t(G) = 128

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

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

GAP

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

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