Presentation

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

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

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

GAP

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

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