Presentation

minimal degreeμ(G) = 26
transitive degreeμt(G) = 512

A minimal faithful permutation representation — 8 generators on 26 points:

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

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