Presentation

minimal degreeμ(G) = 26
transitive degreeμt(G) = 128

A minimal faithful permutation representation — 6 generators on 26 points:

(4,6)(8,10)(11,12,15,16)(13,14,17,18)(19,20)(21,24)(22,23)(25,26);(12,16)(13,17)(19,20)(21,25)(22,23)(24,26);(8,10)(11,13)(12,14)(15,17)(16,18)(19,21,23,26)(20,24,22,25);(8,10)(11,13)(12,14)(15,17)(16,18)(19,22,23,20)(21,25,26,24);(1,2);(3,4)(5,6)(7,8)(9,10)(11,14)(12,13)(15,18)(16,17)(19,21)(20,25)(22,24)(23,26)

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

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