Presentation

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

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

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

GAP

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

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