Presentation

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

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

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

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

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