Presentation

minimal degreeμ(G) = 26
transitive degreeμt(G) = 256

A minimal faithful permutation representation — 7 generators on 26 points:

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

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

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