Presentation

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

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

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

GAP

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

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