Presentation

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

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

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

GAP

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

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