Presentation

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

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

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

GAP

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

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