Presentation

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

A minimal faithful permutation representation — 7 generators on 26 points:

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

GAP

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

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