Presentation

minimal degreeμ(G) = 34
transitive degreeμt(G) = 128

A minimal faithful permutation representation — 5 generators on 34 points:

(1,2);(3,4,6,10,8,11,7,16)(5,12,13,18,15,9,14,17)(19,20,22,26,24,27,23,32)(21,28,30,25,31,33,29,34);(3,5,7,14,8,15,6,13)(4,9,10,17,11,12,16,18)(19,21)(20,25)(22,30)(23,29)(24,31)(26,33)(27,34)(28,32);(19,22,24,23)(20,26,27,32)(21,29,31,30)(25,28,34,33);(3,6,8,7)(4,10,11,16)(5,13,15,14)(9,17,12,18)

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

gap> G := Group((1,2), (3,4,6,10,8,11,7,16)(5,12,13,18,15,9,14,17)(19,20,22,26,24,27,23,32)(21,28,30,25,31,33,29,34), (3,5,7,14,8,15,6,13)(4,9,10,17,11,12,16,18)(19,21)(20,25)(22,30)(23,29)(24,31)(26,33)(27,34)(28,32), (19,22,24,23)(20,26,27,32)(21,29,31,30)(25,28,34,33), (3,6,8,7)(4,10,11,16)(5,13,15,14)(9,17,12,18));
