Presentation

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

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

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

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

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