Presentation

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

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

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

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

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