Presentation

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

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

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

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

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