Presentation

minimal degreeμ(G) = 22
transitive degreeμt(G) = 128

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

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

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

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