Presentation

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

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

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

GAP

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

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