Presentation

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

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

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

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

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