Presentation

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

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

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

GAP

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

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